FIELD: radio engineering, communication.
SUBSTANCE: invention can be used in data transmission systems using phase-shifted signals, without the introduction of redundancy, to maintain bit synchronization for phase-shift keying (PSK) or quadrature-amplitude modulation (QAM) which code constructions use block noise-immune codes. The essence of the method consists in demodulating the received signal, decoding the codewords with error correction and verifying the fact of decoding based on the results of calculating the syndrome. Under the condition of zero syndrome or syndrome corresponding to a given number of errors, the received information block is coded with an noise-immune code, modulated, the correlation properties of the received signal are checked, and the intercorrelation function (ICF) with the signal received from the communication channel is calculated under the specified ACF requirements.
EFFECT: increase of noise-immunity of information transfer.
