ПОДАВЛЕНИЕ ГАУССОВСКИХ И НЕГАУССОВСКИХ ПОМЕХ ПРИ ВЫДЕЛЕНИИ ИМПУЛЬСНОГО СИГНАЛА В БИСПЕКТРАЛЬНОЙ ОБЛАСТИ

Algorithms of noise suppression and compensation in the bispectral region, capable of selecting the desired pulse signal on the background of non-Gaussian and Gaussian disturbances is investigated. A functional in the form of least mean absolute third error is proposed, which makes it possible to apply the optimal filter in the bispectral region in the canceller reference channel. The advantage of the canceller in the bispectral region over compensator, using Wiener filter in the reference channel, is shown. It consists of less sensitive to the uncorrelated Gaussian noise in the channels, that is confirmed by the results of computer simulation.
