FIELD: radio communications; broad-band signal communication systems. SUBSTANCE: device has noise suppressor 1 incorporating noise evaluation unit 2, synchro-phase filter 3, attenuator 4, subtracter 5, switched narrow- band filters 6-6N, and adder 7, correlation receiver 8 incorporating input amplifying, converting, and filtering unit 9, multiplier 10, output integrating unit 11, signal copy generator 12, delay element 13, and noise analyzer made in the form of N frequency channels 141-14N. EFFECT: improved immunity to narrow-band noise due to noise filtering not only by synchro-phase filter that also affords locking of noise initial phases to those at device input but also due to disconnection of switched narrow-band filters suffering noise. 1 dwg
