FIELD: radio engineering; radio communications; receiving digital messages in digital-message separate-transmission mobile-communication burst-error radio links. SUBSTANCE: during separate transmission with digital addition of message encoded by simple code with parity check, error is detected by counting odd number of ones in digital message provided by decoding unit 5 and by adding in modulo two message signals arriving from outputs of computing units 1 of separate reception circuits with aid of adder 4 to locate error and correct it in second shift register 7 by inverting erroneous data bit in received digital message. EFFECT: improved noise immunity in receiving digital signals using parity check coding in two receiving channels. 8 dwg
