Приведены теоретические сведения о OFDM-сигналах, а также сделан обзор известных подходов к оценке временного смещения. Проведено моделирование предложенного и известных методов. Приведен анализ результатов моделирования. В заключении сделаны выводы о работе.</p></abstract><trans-abstract xml:lang="en"><p>This article is devoted to the development of methods for estimating signals time offset with orthogonal frequency multiplexing, making it possible to improve the accuracy of the estimation in comparison with known existing methods. Theoretical information about OFDM signals is presented, an overview of known approaches for estimating time offset is made. The proposed and known methods are simulated. The analysis of simulation results is carried out. The conclusions about the work are given.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>корреляционная обработка</kwd><kwd>оценка временного смещения</kwd><kwd>двухэтапный алгоритм</kwd><kwd>моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>OFDM-сигналы</kwd><kwd>correlation processing</kwd><kwd>OFDM signals</kwd><kwd>estimation of time displacement</kwd><kwd>two-stage algorithm</kwd><kwd>simulation</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">Paichard Y., Inggs М.
