FIELD: radio engineering; broadband signal communication systems. SUBSTANCE: receiving device has protective unit, pseudorandom sequence generator, correlator and spectrum distortion evaluation unit, logic circuit, and delay unit. Cut in protective unit are noise-affected spectrum sections formed due to deflection of some of protective unit strips. Spectrum distortion evaluating unit functions to detect noise-affected sections. Logic circuit serves to determine amount of pseudorandom sequence shift by quantity and location of connected strips. Noise immunity of proposed device is higher by 3-5 dB in case 80% of protective-unit strips are disconnected. EFFECT: enhanced noise immunity, reduced signal detection time. 1 cl, 3 dwg
