Abstract
In the letter a new technique for increasing the efficiency of an automatic-repeat-request communication system is described. This technique uses all the received versions of a codeword, and also those versions containing errors. Such a strategy, together with a soft demodulation of each received symbol, is particularly efficient when applied to ARQ schemes in which each block erroneously received is retransmitted many times.Keywords
