Для его корректного применения к дискретным конструкциям системы OFDM линейная свертка отсчетов заменена круговой сверткой. Такой подход к анализу синхронизации снижает вычислительную сложность его проведения и не требует формирования тренировочных последовательностей либо пилотных данных. В результате получена матрица, учитывающая отклонения анализируемых отсчетов в виде случайных гауссовских процессов с нулевым средним значением, позволяющая оценить амплитуды поднесущих при произвольном уровне дисперсии случайных процессов.</p></abstract><trans-abstract xml:lang="en"><p>The results presented research OFDM system synchronization by using one of the basic properties of the continuous Fourier transform, characterized by the duality between a convolution in the time domain, and multiplying the frequency domain, which is not fully extended to the discrete case. For its correct application to the digital system design OFDM linear convolution sampling replaced the circular convolution. This approach reduces the computational analysis synchronization of its complexity and requires the formation of training sequences or pilot data. The result is a matrix that takes into account the deviation of the analyzed samples in the form of random Gaussian processes with zero mean value, allowing to estimate the amplitude of the subcarriers for an arbitrary level of dispersion of random processes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>синхронизация</kwd><kwd>ортогональный</kwd><kwd>частота</kwd><kwd>разделение</kwd><kwd>мультиплексирование</kwd><kwd>система</kwd><kwd>демодуляция</kwd><kwd>ошибка</kwd><kwd>поднесущая</kwd></kwd-group><kwd-group xml:lang="en"><kwd>synchronization</kwd><kwd>orthogonal</kwd><kwd>frequency</kwd><kwd>division</kwd><kwd>multiplexing</kwd><kwd>system</kwd><kwd>demodulation</kwd><kwd>error</kwd><kwd>subcarrier</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">Peled A., Ruiz A.
