The invention relates to electric communication and is meant for bleaching in communication systems in case of interferences having a spectrum which differ from the flat noise spectrum. Moreover, an interference canceller, an adder, a subtract unit, a filter with regulated amplitude-frequency response, a delay line, an interference spectrum analyzer are introduced. Moreover, an additive mixture of useful signal and interference is supplied simultaneously to the inputs of interference canceller and delay line, also to the subtract unit first input, the interference canceller output is connected to the adder first input and simultaneously to the second input of subtract unit, whose output is connected to the second input of adder, output of the last is connected to input of a data receiver, the delay line output is connected to the input of interference spectrum analyzer, whose output is connected to the second input of filter with regulated amplitude-frequency response. The technical result is filter circuit simplification, signal distortion reduction. |
