Hybrid Error Control Using Retransmission and Generalized Burst-Trapping Codes.

摘要

On most real channels hybrid error control schemes are expected to provide a throughput higher than that of automatic repeat-request (ARQ) systems and a reliability better than forward error correction (FEC) systems. On compound channels, channels with a mixture of random and burst errors, generalized burst-trapping (GBT) codes seem to be quite effective for FEC. In this paper, a hybrid scheme with Go Back N ARQ as the retransmission component and GBT code as the FEC component, is described. Its performance is analyzed in terms of through-put efficiency and undetected error probability and is compared with that of a forward acting GBT code. Numerical calculations of the parameters are presented to illustrate the performance. (Author)
