Abstract

A new coding scheme is presented. In this scheme a given t-error-detecting code is used for transmission over a noisy channel. When t or less errors are detected, a single request is made via a feedback channel for transmission of additional redundancy to enable the decoder to correct t or less errors. It is shown to be superior to forward error correction in rate and probability of error. For low channel errors the resulting rate is higher than that of retransmission with no significant difference in the probability of error.
