Сигналы с многопозиционной фазовой манипуляцией (М-ФМ), обладающие хорошими спектральными и энергетическими характеристиками, успешно применяются во многих системах передачи информации, таких, как системы спутниковой связи, GPS, ГЛОНАСС, DVB/DVB-S2, в наборе стандартов беспроводной связи IEEE 802.11. В каналах радиосвязи на полезный сигнал действуют, кроме шумовой, разные помехи, одной из них является гармоническая, которая при большой интенсивности практически разрушает прием сигналов М-ФМ. Одним из важных требований, предъявляемых к качеству передачи данных, является устойчивость системы к ошибкам. Существуют разные способы повышения качества передачи информации, один из которых – применение технологии корректирующего кодирования. Цель статьи – оценка помехоустойчивости когерентного демодулятора сигналов М-ФМ с применением кодов Хэмминга (7,4) и (15,11) и сверточного кодирования с алгоритмом декодирования Витерби (7,5) при приеме сигналов М-ФМ в условиях воздействия в канале связи шумовой и гармонической помех.Методы. Использованы методы статистической радиотехники, теории оптимального приема сигналов и компьютерного имитационного моделирования.Результаты. С помощью компьютерного имитационного моделирования получены экспериментальные зависимости вероятности битовой ошибки от отношения сигнал/шум и от интенсивности гармонической помехи для когерентного приема сигналов М-ФМ в канале с шумовой и гармонической помехами без применения корректирующих кодов и с применением кодов Хэмминга (7,4) и (15,11), сверточного кодирования с алгоритмом декодирования Витерби (7,5).Выводы. Показано, что применение корректирующих кодов позволяет эффективно исправлять ошибки при наличии шумовой и гармонической помех с малой интенсивностью. При большой интенсивности помехи коррекция неэффективна. Результаты могут служить важным руководством при проектировании надежных и энергоэффективных систем передачи информации. </p></abstract><trans-abstract xml:lang="en"><p>Objectives. Signals with multiple phase shift keying (M-PSK) exhibiting good spectral and energy characteristics are successfully used in many information transmission systems. These include satellite communication systems, GPS, GLONASS, DVB/DVB-S2, and a set of IEEE 802.11 wireless communication standards. In radio communication channels, the useful signal is affected by various interferences in addition to noise. One of these is harmonic interference. As a result, high intensity harmonic interference practically destroys the reception of M-PSK signals. One of the important requirements for the quality of data transmission is the system error tolerance. There are different ways of improving the quality of information transmission. One of these is the use of corrective encoding technology. The aim of the paper is to assess the noise immunity of a coherent demodulator of M-PSK signals using Hamming codes (7,4) and (15,11), and convolutional encoding with Viterbi decoding algorithm (7,5) when receiving M-PSK signals under noise and harmonic interference in the communication channel.Methods. The methods of statistical radio engineering, optimal signal reception theory and computer simulation modeling were used.Results. Experimental dependencies of the bit error rate on the signal-to-noise ratio and on the intensity of harmonic interference of coherent reception of M-PSK signals in a channel with noise and harmonic interference were obtained using computer simulation modeling. This was done without using correction codes and with Hamming code (7.4) and (15.11) and convolutional encoding with Viterbi decoding algorithm (7,5).Conclusions. It is shown that the application of the correction codes effectively corrects errors in the presence of noise and harmonic interference with lower intensity. The correction is ineffective in the presence of high intensity interference. These results can provide important guidance in designing the reliable and energy efficient system.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>многопозиционная фазовая манипуляция</kwd><kwd>корректирующие коды</kwd><kwd>код Хэмминга</kwd><kwd>сверточный код</kwd><kwd>алгоритм декодирования Витерби</kwd><kwd>помехоустойчивость</kwd><kwd>вероятность битовой ошибки</kwd><kwd>гармоническая помеха</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multiple phase shift keying</kwd><kwd>correction codes</kwd><kwd>Hamming code</kwd><kwd>convolutional encoding</kwd><kwd>Viterbi decoding algorithm</kwd><kwd>noise immunity</kwd><kwd>bit error rate</kwd><kwd>harmonic interference</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Abu-Baker A., Bani-Hani K., Khasawneh F., Jaradat A.
