FIELD: computer equipment.
SUBSTANCE: invention relates to computer engineering and communication and can be used to decode a noise-immune code when transmitting, storing, reading and recovering digital data. Binary information and redundant code symbols received in the decoder from the communication channel are converted into symbols of the information register, into symbols of the syndrome register and into symbols of the difference register, which are successively corrected based on the operation results of the threshold element, wherein in addition, for symbols nearest to the decoded information, in the information, syndrome and difference registers, plausible error combinations are determined, and the result of triggering the threshold element is generated based on the most plausible error combination.
EFFECT: technical result consists in improvement of probability of correction of errors during decoding in conditions of high level of noise in communication channels.
