FIELD: electrical communications, computer engineering; data transfer systems incorporating provision for duplicating messages.
SUBSTANCE: proposed method provides for enhanced probability of data reception due to use of information about combinations received earlier followed by choice of most reliable combination. Choice is effected by way of majority decoding and search of combinations including superposition of probable error vectors onto distorted information blocks already received. Decoding of 99.97% of information code blocks is guaranteed in channel where number of distortions corresponds to code correction capability and more than 90% of information messages incorporating 200 code blocks are guaranteed at triple transfer of three times transferred messages in channel where number of distortions is twice as great as code correcting capability.
EFFECT: enhanced reliability of data received.
