Abstract. In this paper, an algorithm for preprocessing of PSK - signals based on wiener filtration is proposed. The aim of preprocessing is to extract the phase discontinuities when filtering harmonic filling of a signal. This method allows us to avoid compensation of unknown frequency shift in the problems of determining the time delay of signals during multichannel propagation. The study checks the conditions of algorithm applicability and its stability to a noise level in the observed channels.

Key words: signal detection, mutual time delay, Capon's minimum variance method, Wiener filtering.
