Abstract :
We consider spatially-coupled LDPC codes for the three terminal erasure relay channel. It is observed that BP threshold value of spatially-coupled LDPC codes, in particular spatially-coupled MacKay-Neal code, is close to the theoretical limit for the relay channel. Empirical results suggest that spatially-coupled LDPC codes have great potential to achieve theoretical limit of a general relay channel.
