Type-I and type-II Reed-Muller hybrid-ARQ protocols
Stephen B. Wicker, Michael J. Bartz · 2002
It is shown that the Green machine decoder can be modified to allow for the use of first-order Reed-Muller codes in both type-I and type-II hybrid-automatic-repeat-request (ARQ) protocols. The type-I protocols offer substantially better reliability performance than their forward error correction (FEC) counterparts, though at the expense of a reduction in throughput at low signal-to-noise ratios. The type-II protocols offer similar reliability performance to that provided by the type-I protocols, but offer much better throughput performance at low SNRs.>
