Kirish) Yitran tomonidan. 3-jadvalda sanab o‘tilgan sxemalar ikkita asosiy mezon bo‘yicha taqqoslanadi: chastota diapazonining samaradorligi va narxi. 3-jadval.

Ularning parametrlari 3-jadvalda umumlashtirilgan. Biroq, butun dunyo bo‘ylab yagona PLC standartini qabul qilish hali sodir bo‘lmagan. Bu muammo hozirda IEEE 1901.2 ishchi guruhi tomonidan hal qilinmoqda. Hozirgacha G3-PLC standarti eng ishonchli hisoblanadi. 4-jadval. Tor polosali PLC-aloqaning standartlari parametrlari.

Volume 2, Issue 2 62 June 2025 Management and Future Technologies journal.umft.uz bilan murakkablashadi. Elektr uzatish liniyalari orqali signalning yaxlitligini ta’minlash ishonchli ma’lumotlarni uzatish texnologiyalari va uskunalarini talab qiladi; elektr ta’minoti tarmog‘ining tuzilishi turli mamlakatlarda turlicha farq qiladi. Xuddi shu narsa uy ichidagi simlar uchun ham amal qiladi. PLC aloqasi yoki elektr tarmoqlari uchun universal standart yo‘q. Turli xil qurilmalar o‘rtasidagi muvofiqlikni ta’minlash uchun tegishli choralar ko‘rish lozim; elektr uzatish tarmoqlari orqali shaxsiy ma’lumotlarni yuborishda ular himoyalangan bo‘lishi kerak. 3.4. Ethernet texnologiyalari. Ethernet texnologiyalari CSMA/CD mexanizmidan (Carrier Sense Multiple Access with Collision Detection) kelib chiqqan, u deyarli hech qanday to‘qnashuvsiz (amalda ko‘plab ulanishlarga kolliziyalarsiz) zamonaviy kommutatsiyalangan tarmoqlarga aylandi. O‘zgartirilgan Ethernet qurilmalari alohida ishlatiladi va yangi aloqa texnologiyasi (IEU) to‘qnashuvlarni (kolliziyalarni) kamaytirish va bartaraf etishga qaratilgan. Ethernet kommutator bir nechta portlarga ega. Har bir Ethernet porti IEU ga ulanadi va kichik tarmoq segmenti hosil bo‘ladi. Ushbu konfiguratsiya bir nechta qurilmalar o‘rtasidagi tenglikni ta’minlaydi. Ethernet kommutatorining asosiy vazifasi ─ manzil nazorati asosida axborotni jo‘natuvchi va qabul qiluvchi o‘rtasida to‘g‘ridan-to‘g‘ri xabarni o‘rnatishdan iborat. Zamonaviy mahalliy tarmoqlardagi kommutatsiya mexanizmlari ma’lumotlar uzatishni tezlashtiradi va soniyasiga bir necha gigabitgacha tezlikka erishish imkonini beradi. O‘tkazilgan va qabul qilingan trafikni ajratish uchun o‘ralgan juftlik va optik tolali kabellardan foydalangan holda zamonaviy kommutatsiyalangan LAN tarmog‘ida media to‘qnashuvisiz (kolliziyasiz) to‘liq dupleks yaratish mumkin. Bundan tashqari, istiqbolli texnologiyalar real vaqt rejimida muhim nazorat vazifalarini amalga oshirish uchun deterministik (belgilangan qiymatdan oshmaydigan) uzatish vaqtiga ega bo‘lgan aloqa (bog‘lanish) protokolini amalga oshirishga imkon beradi [9]. Ethernet kommutatori ─ bu har bir portda qabul qilingan yoki uzatilgan barcha xabarlarni qayta ishlaydigan yuqori tezlikdagi, past kechikishli almashtiruvchi kalit. Vaqtni kechiktirish sodir bo‘lganda, qo‘shimcha almashtirish (kutish navbatida) joriy etiladi va xabarlarni keyingi tarqatish bilan xotirada oraliq saqlash amalga oshiriladi. Agar xabar o‘z manziliga yetib borishi uchun bir nechta tarmoq kalitlarini bosib o‘tishi kerak bo‘lsa, umumiy eng yomon holatda uzatish vaqti har bir kalitlarning kechikishlari yig‘indisidir. 3.5. Radiotexnologiyalar. Simsiz va simli aloqa texnologiyalari o‘rtasidagi farqlarga e’tibor qaratamiz. Simli texnologiyalarning afzalliklari:

Management and Future Technologies journal.umft.uz June 2025 Volume 2, Issue 2 1-10 Gbit/s-gacha yuqori uzatish tezligi (o‘zidan o‘tkazish qobiliyati); kommunikatsiya sistemasidagi kichik kechiktirishlar; (boshqalarga) solishtirilganda yuqori himoyalanganlik. Simli texnologiyalarning kamchiliklari: Kabelning shikastlanishi yoki sinish ehtimoli mavjud. Yer osti kommunikatsiya holatlari uchun zararni bartaraf etish murakkab, qimmat va vaqt talab qilishi mumkin; yomon bog‘lanish shovqinlarga yoki uzilishlarga (uzilib-uzilib ishlashga) olib keladi; metall simlarda xabarlarni o‘g‘irlikcha tinglash imkoniyati; ob’yektlarning harakatsizligi tufayli aloqa tarmog‘ining konfiguratsiyasini o‘zgartirish qiyinligi; metall simlar podstansiyalarda potensial o‘tkazishga sezgir. Simsiz texnologiyalarning afzalliklari: Simli tizimlarga qaraganda arzonroq va tezroq joylashtirish; simsiz aloqa tufayli o‘rnatish qulayligi; portativ, uskunani boshqa ob’yektga osongina ko‘chirish mumkin; simsiz uskunalar xavfsizlik va kirish talablarini ta’minlab, avtomatik ravishda mavjud simsiz tarmoqqa ulanishi mumkin; yer potensialini olib tashlash uchun kamroq sezgir. Simsiz texnologiyalarning kamchiliklari: elektromagnit shovqin va noma’lum nurlanishlarining ta’siri; ma’lumotlarni uzatish tezligi (54-160 Mbit/s)ning pastligi; kanal ishonchliligi/mavjudligining pastligi; radio efirdan foydalanish tufayli kiberxavfsizlik muammolari. Keling, energiya hisobini avtomatlashtirishda qo‘llaniladigan ikkita istiqbolli simsiz texnologiyalarni ko‘rib chiqaylik. Uyali aloqa GSM (Global System for Mobile Communications) 3G/4G texnologiyasining uyali aloqalari (uchinchi/to‘rtinchi avlod) 824-894 MGs, 1900 MGs chastota diapazonlarida ishlaydi. Bu lisenziyalangan chastota diapazonlari. Ma’lumot uzatish tezligi 60 kbit / s dan 300 Mbit/s gacha o‘zgarib turadi va masofa uyali tayanch stansiyalarni joylashtirish bilan belgilanadi. Uyali tarmoqning 63

Volume 2, Issue 2 64 June 2025 Management and Future Technologies journal.umft.uz topologiyasi kam quvvatli uzatgichlarni o‘z ichiga olgan tayanch stansiyalarni joylashtirish orqali shakllanadi. Uyali modemga ega bo‘lgan mobil qurilma ma’lumotlarni uyadan uyaga uzluksiz uzatish orqali ma’lumot almashish imkoniyatiga ega. Shunday qilib, nuqtadan nuqtaga ulanish tashkil etiladi. Ushbu texnologiya katta maydonlarni qamrab oladi va axborot yig‘ish tizimini yaratish uchun katta xarajatlarni talab qilmaydi. 4.6-rasmda uyali aloqa texnologiyalaridan foydalangan holda tijorat elektr energiyasini hisobga olish tizimini tashkil qilishning mumkin bo‘lgan variantlaridan biri ko‘rsatilgan. Texnologiyaning afzalligi shundaki, u mavjud infratuzilmadan foydalanadi. Shuni ta’kidlash kerakki, mobil ma’lumotlarni uzatish tezligi doimiy ravishda oshib bormoqda. Uyali aloqadan foydalangan holda aloqaning asosiy xususiyatlari quyidagilardan iborat: ulanishni o‘rnatish noma’lum vaqtni oladi; abonent qo‘ng‘iroqlari ma’lumot uzatish tezligiga va ulanishning uzilishiga ta’sir qilishi mumkin; abonent to‘lovlari va uyali aloqa tizimlariga ulanishni tashkil qilish narxi yuqori emas, lekin kichik hududlarda bir nechta aloqa kanallarini tashkil qilish foydasiz bo‘ladi. Zig Bee texnologiyasi Zig Bee dunyodagi (aloqa) protokollari asosida Zig Bee Alliance ittifoqi (alyansi) tomonidan ishlab chiqilgan aqlli (intellektual) uy tarmoqlari uchun ishonchli, iqtisodiy samarali uzatish texnologiyasi bo‘lib hisoblanadi. Bu standartga IEEE 802.15.4 mos keladi va lisenziyalangan 868 MGs, 915 MGs i 2,4 GGs chastota diapazonlarida ishlaydi [10]. 6-rasm. Elektr energiyani tijoriy qayd qilish sistemasi realizatsiyasiga misol. Ma’lumotlar uzatish tezligiga 10 − 100 m masofada erishish mumkin – 20 − 250 kbit/s. Zig Bee

Management and Future Technologies journal.umft.uz June 2025 Volume 2, Issue 2 «yulduz», «daraxt» va boshqa topologiyalarni qo‘llab-quvvatlaydi va ma’lumotlarni uzatish tezligi sezilarli darajada tanlangan topologiyaga bog‘liq. Zig Bee texnologiyasi xavfsiz aloqa uchun 128-bitli AES shifrlashdan foydalanadi. Zig Bee binolarni avtomatlashtirish, ularning xavfsizlik tizimlari, masofadan boshqarish va o‘lchash uchun keng qo‘llaniladi. Muhokama O‘tkazilgan tadqiqot ENHAT tizimlarida turli kommunikatsion topologiyalar va protokollarni tanlashda aniqlik kiritishga yordam berdi. Ma’lumotlar shuni ko‘rsatadiki, topologiya tanlovi tizimning hajmi, tuzilishi, ishonchlilik talablari va iqtisodiy imkoniyatlariga bog‘liq. Masalan, shina topologiyasi kichik va sodda tizimlar uchun tejamkor echim bo‘lsa, mesh topologiyasi yuqori ishonchlilik va uzluksizlikni talab qiladigan muhitlarda samarali hisoblanadi. Xuddi shunday, yulduz topologiyasi nosozliklarni tez aniqlash va markaziy monitoring imkoniyati bilan ajralib turadi, biroq markaziy bog‘lovchi qurilmaning ishdan chiqishi butun tarmoq faoliyatiga salbiy ta’sir ko‘rsatadi. Protokollar bo‘yicha tahlil shuni ko‘rsatdiki, RS-485 va CAN protokollari sanoat muhiti uchun mos, chunki ular uzoq masofali va ko‘p tugunli aloqani ishonchli tarzda ta’minlaydi. RS-485 oddiy tuzilma va arzon uskunalari bilan ajralib tursa, CAN protokoli yuqori ustuvorlik asosida real vaqtli signal uzatishni qo‘llab-quvvatlaydi. Ethernet esa, yuqori o‘tkazuvchanlik, kam kechikish va to‘liq dupleks ishlash tufayli real vaqtli nazorat uchun eng afzal hisoblanadi. Simsiz texnologiyalardan GSM keng qamrovli energiya hisoblash tizimlari uchun foydali bo‘lsa, ZigBee kam quvvat sarfi, xavfsizlik va qisqa masofalardagi samaradorligi bilan ajralib turadi. Shuningdek, ZigBee'ning "mesh" arxitekturani qo‘llab-quvvatlashi uni moslashuvchan va kengaytiriladigan tarmoqlar uchun muhim qiladi. Bu natijalar ilgari o‘rganilgan manbalar bilan mos tushadi. Masalan, Smith (2024) energiya tizimlaridagi ikki tomonlama kommunikatsiya tarmoqlari energiya samaradorligini sezilarli darajada oshirishini ta’kidlaydi [4]. Shuningdek, IEEE 61850 standarti asosida avtomatlashtirilgan podstansiyalarni tashkil qilishda real vaqt rejimida ma’lumot uzatish vaqti kritik ahamiyatga ega ekanligi ko‘rsatilgan [3]. Kelgusida ushbu tizimlarning model asosida (simulyatsion) baholash va prototip sinovlari orqali yanada chuqurroq tahlil qilish mumkin. Ayniqsa, energetik tizimlardagi shovqinli muhitda signalning buzilishiga chidamli aloqalar ustida ishlash va xavfsizlik bo‘yicha tadqiqotlar dolzarb bo‘lib qolmoqda. 65

Volume 2, Issue 2 June 2025 Management and Future Technologies journal.umft.uz Xulosa 66 Ushbu maqolada ENHAT texnologiyalarida qo‘llaniladigan turli kommunikatsion topologiyalar va protokollar tahlil qilindi. Tadqiqot natijalari shuni ko‘rsatdiki, har bir topologiya va aloqa protokolining o‘ziga xos texnik va funksional xususiyatlari mavjud bo‘lib, ularni tanlashda quyidagi asosiy mezonlar inobatga olinishi lozim: uzatish masofasi, tezlik, tarmoqning kengaytiriluvchanligi, ishonchlilik, kechikish darajasi va iqtisodiy samaradorlik. Kichik hajmdagi, past quvvatli ilovalar uchun RS-232 protokoli va shina/yulduz topologiyalari samarali bo‘lsa, sanoat avtomatizatsiyasida keng ishlatiladigan RS-485 va CAN protokollari ishonchliligi va ko‘p tugunli almashinuvga imkon beruvchi imkoniyatlari bilan ajralib turadi. Yuqori o‘tkazuvchanlik, minimal kechikish va ishonchlilik talab etiladigan tizimlarda esa Ethernet texnologiyalari ustunlik qiladi. Shuningdek, simsiz texnologiyalar – GSM va ZigBee – uzoq masofali va mobil qurilmalar uchun muhim yechimlar hisoblanadi. Ayniqsa ZigBee texnologiyasi xavfsizlik, kam quvvat sarfi va modullilik talab etiladigan zamonaviy energiya hisoblash tizimlari uchun istiqbolli yo‘nalish bo‘lib qolmoqda. Natijalar shuni ko‘rsatadiki, ENHAT tizimlarini samarali loyihalashda yagona aloqa texnologiyasiga tayanish o‘rniga, tizim xususiyatlariga qarab bir nechta protokol va topologiyani birlashtirgan kompleks yondashuv eng maqsadga muvofiqdir. Ushbu tahlil asosida ishlab chiqilgan tavsiyalar amaliy loyihalarda kommunikatsion echimlarni tanlash va optimallashtirishda foydali bo‘lishi mumkin.

Management and Future Technologies journal.umft.uz COMPARISON OF CORRECTING CAPABILITY OF BLOCK CODES A bstract: This paper discusses the comparative errorcorrecting ability of block codes such as Hamming, Golay, BCH, and Reed-Solomon codes. The introduction emphasizes the importance of ensuring reliable data transmission under real-world interference conditions such as thermal noise, multipath propagation, and impulse interference. Methods for improving noise immunity are discussed, including convolutional and block coding. The paper presents analytical formulas for calculating the probability of errors in decoded messages using various codes. The calculation results confirm that the error-correcting ability depends on the code parameters and the error probability in the channel. A study is conducted on the efficiency of codes in the presence of burst errors of different lengths, including conditions under which decoding remains successful. The paper emphasizes that the choice of the optimal code is determined by the specifics of the telecommunication system and the characteristics of the communication channel. Keywords: Hamming, communication chanel, decoded message, information transmission.

Management and Future Technologies journal.umft.uz June 2025 Volume 2, Issue 2 Introduction Information plays an increasingly important role in all types of human activity. Recently, the requirements for information transmission systems have increased dramatically. It is necessary to transmit ever greater volumes of information over ever greater distances at ever greater speeds. At the same time, the transmitter's energy resources are usually limited. The requirements for the reliability of data transmission are also growing. In recent years, methods of digital processing and transmission of information in various telecommunication systems have significantly developed. One of the most important functions in the operation of such systems is to ensure reliable protection of data from interference. The radio channel is a weak link in data transmission systems, since it is in it that transmitted signals are subject to distortion and attenuation due to the negative impact of numerous factors. Interference and fading reduce the reliability of information transmission. Increasing the reliability of information transmitted over a communication channel can be organized in various ways, for example, by increasing the transmitter power, improving the sensitivity of the receiver, increasing the gain of antennas. The implementation of these methods usually requires significant material costs, and most importantly, does not ensure an increase in the reliability of transmitted information with frequencyselective fading. Increasing the noise immunity of information is achieved in various ways, but many of them are ineffective for one reason or another. For example, increasing the transmitter power is limited by strict requirements for electromagnetic compatibility of radiation sources, and multiple repetition of transmitted blocks leads to a significant increase in channel occupancy and a corresponding increase in the information processing time [1]. At present, the task of ensuring the reliability of information transmission is solved in most cases by using noise-resistant coding, which is a class of signal transformations performed to improve the quality of communication. Modern people are surrounded by devices that use noise-resistant coding algorithms in their work. Noise-resistant coding technologies have become a mandatory element of data storage and transmission systems. The basis of modern coding theory is the work of V.A. Kotelnikov and K.E. Shannon. Subsequently, the theory of noise-resistant coding was developed by many researchers. However, the problem of an unambiguous choice of the type of coding for a specific information transmission channel has not yet been solved. Currently, there are a significant number of options for constructing and decoding methods for error-correcting codes that are capable of correcting both single and group errors. At the same time, the characteristics of practical implementations of error-correcting codes lag significantly behind the theoretical limits. Significant difficulties arise in satisfying the requirements for code efficiency in order to achieve the constantly growing requirements for data transmission and storage systems. 77

Volume 2, Issue 2 June 2025 Management and Future Technologies journal.umft.uz Reasons for deterioration of signal transmission quality 78 The source of interference in an ideal channel is thermal noise generated in the receiver [2, 3, 4]. Thermal noise typically has a constant spectral power density over the entire signal band and a Gaussian voltage probability density function with zero mean. The signal in an ideal channel attenuates with distance in exactly the same way as when propagating in ideal free space. The signal power decreases proportionally to the square of the distance. With such ideal propagation, the signal power is quite predictable. Additional sources of losses in a real radio channel are natural and artificial sources of noise and interference, the negative impact of which is often more significant than the thermal noise of the receiver [5, 6, 7]. In radio communication, signal propagation occurs in the atmosphere and near the earth's surface. A radio signal can travel from a transmitter to a receiver along multiple paths. This phenomenon, called multipath propagation, can cause fluctuations in the amplitude, phase, and angle of arrival of the received signal, which is called multipath fading. Fading causes random fluctuations in the signal. For a typical radio channel, the received signal consists of several discrete multipath components, resulting in a spreading of the signal over time (or signal dispersion). In the case of signal dispersion, the types of degradations due to fading are divided into frequency-selective and frequency-non-selective. In the case of non-stationary channel behavior, the types of degradations due to fading are divided into fast and slow. In addition to independent errors, grouped errors may occur in the channel. They are formed in channels with memory. One of the main causes of such errors are interruptions that occur due to a smooth decrease in the signal level below the receiver's sensitivity threshold, when signal reception practically ceases. Interruptions can be caused by various activities, and some of them can even cause termination of a communication session. In addition, interruptions can be caused by equipment malfunctions, imperfect operation, measurement, etc. Interruptions and impulse interference are the main cause of grouped errors when transmitting discrete messages over various types of communication channels. Impulse interference is interference concentrated in time. It is a random sequence of pulses with random amplitudes and following each other at random time intervals, and the transient processes caused by them do not overlap in time. The most common causes of such interference are: switching connections in electronic equipment, interference from high-voltage lines, lightning discharges, and reception of reflected signals. Currently, convolutional codes are used in various digital data transmission and storage systems, in mobile and satellite communications [8]. Noise-immune codes are quite diverse and differ in the encoding-decoding method, the number of coded information bits, the introduced

Management and Future Technologies journal.umft.uz June 2025 Volume 2, Issue 2 redundancy, and the number of errors corrected. The parameters of noise-immune codes are selected based on the characteristics of a specific digital communications system. Currently, there are three main understandings of efficiency: efficiency in the sense of effectiveness - this is the ability to produce an effect (result) of some actions, which cannot always be measured using quantitative indicators; efficiency in the sense of productivity, performance, economy - this is an indicator of the effectiveness of activities, reflecting the amount of output per unit of costs (the fewer resources spent on achieving the planned results, the higher the productivity); efficiency in the sense of effectiveness, optimality - this is the ability to produce the planned result in the desired volume, can be expressed by a measure (percentage ratio) of the actually produced result to the standard/planned one. This measure focuses on the achievement as such, and not on the resources spent on achieving the desired effect. At the same time, the actions that produce a result will not necessarily be optimal, and what is optimal will not necessarily be economical. Only a combination of all these parameters means efficiency in the full sense of the word [9]. Quantitatively, efficiency is assessed using an efficiency indicator [10]. Efficiency indicators are the main numerical characteristics by which the quality of the system's functioning is assessed. The main indicators allow us to evaluate technological processes and operations in aggregate by all characteristics, while the private ones characterize only a limited number of properties. Determining the composition and content of the system of indicators necessary for conducting an efficiency assessment is a classic task of systems analysis [11, 12]. Based on the analysis of modern educational literature [1, 9, 11], in the part concerning errorcorrecting coding, the main indicators are: - code rate; - probability of a bit error in a decoded information message; - energy gain from the use of error-correcting coding; - spent computing resources; - complexity of hardware implementation. The efficiency of error-correcting coding is assessed according to certain evaluation criteria. Criterion - 1) means for making a judgment; standard for comparison; rule for evaluation; 2) measure of the degree of closeness to the goal. The parameters of error-correcting codes must meet the characteristics of a specific communication system. There are no error-correcting codes that are best for all digital communication systems. Approaches to assessing the effectiveness of error-correcting codes may vary. 79

Volume 2, Issue 2 80 June 2025 Management and Future Technologies journal.umft.uz One of the widespread and actively developing methods for increasing the efficiency of errorcorrecting codes is to combine codes. Convolutional codes are one of the large classes of errorcorrecting codes. Hamming codes form one of the best-known families of linear block codes [13, 14, 15, 16, 17]. For every natural number m ≥ 3, there exists a binary Hamming code with the following parameters: - length of code words n 2m 1 ; - number of information bits k 2 m 1 m ; - number of verification digits m n k ; - corrective ability t 1 , d min 3 . The Hamming code requires minimal redundancy for a given block length to correct one error. The Hamming code is a perfect code. The advantage of this code is its simplicity and, as a result, high encoding and decoding speeds. The disadvantage is the ability to correct only single errors. Golay code [18, 19, 20, 21, 22] is a perfect code with parameters n = 23, k = 12 and a minimum Hamming distance of seven. This code guarantees the correction of all three-bit errors. The advantage of this code is a relatively simple decoding algorithm and the ability to withstand three-bit errors. The Golay code (23,12) has a generating polynomial g ( x) x11 x10 x 6 x5 x 4 x 2 x . The Golay code is encoded by implementing polynomial division. Decoding the Golay code is usually done using the Meggitt decoder. Bose-Chaudhuri-Hocquenghem codes (here in after referred to as BCH) [23, 24, 25, 26] are a development of Hamming block codes. This type of code provides greater freedom in choosing the block length, degree of coding, alphabet size, and error correction capabilities. Theoretically, BCH codes can correct an arbitrary number of errors. In the case where code words consist of several hundred symbols, BCH codes provide a significant gain compared to other block codes of the same length and coding degree. Most often, BCH codes use code words of length n 2 h 1 , where h = 3, 4, 5… For BCH codes, the maximum coding efficiency is achieved with coding degrees between 1/3 and 3/4. From a mathematical point of view, the construction of BCH codes is based on the operation of calculating the remainder from dividing the vector of the information word by a generating polynomial. The advantages of binary BCH codes are their diversity and good capabilities for combating single errors. The disadvantages are rather complex decoding algorithms (especially for long codes) and the inability to resist error bursts.
