FIELD: systems for message transmission over communication channels suffering additive correlated noise. SUBSTANCE: noise suppresser uses correlation function read-out shaping unit for implementing correlation principle of discriminating lumped noise along with connection of first and second adaptive filters to noise separation channel; first and second inputs of correlation function read-out shaping unit function as device inputs and their first and second outputs are connected to first and second adaptive filters, respectively; third output is connected to first input of adaptive filter control factor computing unit. EFFECT: improved reliability of noise suppression, capability of operating under a priori uncertain conditions concerning noise properties. 4 dwg
