Erasure-correcting vs. erasure-detecting codes for the full-duplex binary erasure relay channel

International audienceIn this paper, the asymptotic iterative performance of block-Markov, sparse-graph codes over the binary erasure relay channel is investigated. Note that the full-duplex relay channel is a particular case of the considered model. We obtain two interesting results: a) the block-Markov structure does not improve the asymptotic performance of good erasure-correcting sparse-graph codes; b) under certain conditions, it does however improve the asymptotic performance of good erasure-detecting (i.e. bad erasure-correcting) sparse-graph codes
