Abstract: Изобретение относится к области создания систем телекоммуникаций обмена информацией акустическими речевыми сигналами в условиях внешних акустических помех. Изобретение может быть использовано в системах громкоговорящей связи (ГГС), в оперативно-командных управляющих телекоммуникационных системах аудио обмена, которые характеризуются наличием внешних акустических помех - эхо-сигналов. Достигаемый технический результат - повышение эффективности подавления эхо-сигналов в системах телекоммуникаций ГГС по критерию уровня компенсации отраженных эхо-сигналов, обеспечивается вводом в устройство компенсации блока из нескольких адаптивных фильтров, каждый из которых обеспечивает компенсацию сигналов эха только в своем диапазоне задержек, локализованных в окрестности долговременного параметра задержки. Для определения долговременных параметров эха и их числа, для определения числа каналов компенсации, в устройстве компенсации осуществляется вычисление взаимной корреляционной функции (ВКФ) оцифрованного сигнала, полученного на выходе микрофона, и опорного сигнала коррелятора, полученного в блоке формирования кадров и задержек. По значению ВКФ и энергии опорного сигнала R(kT), R(0), осуществляется оценивание долговременных параметров эха: оценивание задержки эхана k-ом интервале задержек и оценивание затухания эхаотносительно энергии опорного сигнала коррелятора, применяя алгоритм выделения локальных экстремумов в блоке вычисления долговременных параметров. По оценкам долговременных параметров формируется модель эхо сигналов для формирования опорного сигнала адаптивного фильтра L-го порядка k-го канала. Алгоритм адаптивной компенсации эха состоит из формирования матрицы опорного сигнала, коррекции коэффициентов адаптивного фильтра алгоритмом адаптации, коррекция матрицы по минимизированному значению ошибки оценивания задержки эха - Δ, итерационная минимизация ошибки оценивания задержки эха. При достижении минимизированной ошибки оценивания задержки эха в устройстве компенсации осуществляется наиболее полная компенсация эхо-сигнала, отраженного с задержкой. 7 ил.
