摘要: A novel method for visualising the convergence behaviour of iterative decoding schemes is proposed. Each constituent decoder represented by a mutual information transfer characteristic which describes flow extrinsic through soft in/soft out decoder. The exchange between decoders plotted in an chart. concepts are illustrated demapping and scheme.
