FIELD: radio communications in signal receipt mode.
SUBSTANCE: the technical effect is achieved because receiving device contains k frequency transformers and band filtering blocks with amplitude detection, analysis block, synchronization block, k blocks for generating leaping frequency, k controllable attenuators, adder, attenuator control block and block for forming time intervals, interconnected in a certain way.
EFFECT: increased interference resistance under effect of powerful interference of concentrated frequency.
