A technique is considered for enhancing the noise immunity of broadband communications systems with repetition. This technique is based on generating a broadband noise-like signal in the transmitting circuit of the system and adaptive compensation of broadband localized interferences in the receiver. In this case, an adaptive variation of transmitter carriers is conducted in each of the channels. The gain in noise immunity provided by the technique proposed was calculated in comparison with other known techniques.
