Using Channel Output Feedback to Increase Throughput in Hybrid-ARQ
Using Channel Output Feedback to Increase Throughput in Hybrid-ARQ
Hybrid automatic repeat request (ARQ) protocols have become common in many packet transmission systems due to their incorporation in various standards. Hybrid-ARQ combines the normal ARQ method with forward error correction (FEC) codes to increase reliability and throughput. In this paper, we look at improving upon this performance using feedback …
