EFFICIENT ARQ SCHEMES FOR POINT-TO-MULTIPOINT COMMUNICATION

摘要

The use of forward error correction (FEC) and multiple copy decoding (MCD) in point-to-multipoint ARQ schemes are studied.Three different channel models are considered:(1) a binary symmetric channel,(2) a non-fading additive white Gaussian noise (AWGN) channel,and (3) a Rayleigh fading AWGN channel.It is found that both FEC and MCD can yield significant throughput improvements.
