FIELD: radio communication, in particular, transmission of digital messages through communication channels. SUBSTANCE: device has input signal converting unit, which output is connected to input of delay line which has 2M-1 taps. One end of delay line is connected to first input of unit which estimates pulse reaction. All other outputs of delay line are connected to 2M first inputs of compensator of inter-character distortions. M second inputs of compensator are connected to M outputs of pulse reaction estimation unit. 2M third inputs of compensator are connected to 2M outputs of 2M-bit shift register, which input is connected to output of comparison unit. M outputs of 2M-bit shift register are connected to second inputs of pulse reaction estimation unit. (2M-2) outputs of inter-character distortion compensator are connected to (2M-1) first inputs of first and second calculation unit, which additional first input is connected to another output of delay line. M second inputs of first calculation unit are connected to M outputs of pulse reaction estimation unit. In addition device has first unit which calculates weights, M(M+1) adders with N inputs, first and second units which solve systems of linear algebraic equations, and M second units which calculate weights. M inputs of first weight calculation unit are connected to M outputs of pulse reaction estimation unit. M outputs of first calculation unit and M2 outputs of first weights calculation unit are connected through M(M+1) adders with N inputs to M first inputs and M2 second inputs of first unit which solves systems of linear algebraic equations. M outputs of first unit which solves systems of linear algebraic equations are connected to first M inputs of second unit which solves systems of linear algebraic equations. M2 second inputs of first unit which solves systems of linear algebraic equations are also connected to second M2 inputs of all M second weight calculation units. M groups of M2 second inputs of first unit which solves systems of linear algebraic equations are also connected to M first inputs of corresponding M second weights calculation units which M outputs are connected to corresponding M groups of M2 second inputs of second unit which solves systems of linear algebraic equations. Output of latter unit is connected to input of comparison unit which output serves as device output. Device design provides possibility of mutual compensation of shifts of transmitted message characters. EFFECT: increased stability to noise (decreased probability of error) while keeping high transmission speed. 6 dwg
