FIELD: radio engineering. SUBSTANCE: invention can be used in communication systems for reception of digital signals under conditions of uncertain interference. Radio receiver of digital signals has antenna, low-noise amplifier, receiver with demodulator, computer, unit of carrier shift, high-frequency switch, attenuator and noise generator. Increase of noise immunity of reception is based on phenomenon consisting in decrease of probability of error of reception of digital signals under conditions of effects of optimized harmonic noises with additional increase of background noise. EFFECT: increased noise immunity under effects of optimized harmonic noises with limited average power. |
