Abstract :
In this work, we propose a method for digital filtering of phase-shift keyed signals. The method, based on phase break allocation of initial signals, is realized as an information-optimal linear filter and makes it possible to avoid unknown frequency shift compensation in the problems of determining the time delay of signals during the multichannel propagation. The developed algorithm supposes simple realization in real time on the basis of the digital logic integrated scheme.
