FIELD: radio engineering; communication systems. SUBSTANCE: method is based on multiplying input mixture with respective reference sync signal in each of N channels and comparison of discriminated envelope with second threshold value in each of N channels followed by multiplying filtered-off signal with same reference sync signal to recover signal received by this channel which is subtracted from input mixture at channel input wherein time excess of two threshold values has not been detected. EFFECT: enhanced noise immunity. 3 dwg
