摘要: Mutual information transfer characteristics for soft in/soft out decoders are proposed as a tool to better understand the convergence behavior of iterative decoding schemes. The exchange extrinsic is visualized trajectory in Extrinsic Information Transfer Chart. This allows prediction turbo cliff position and bit error rate after an arbitrary number iterations. influence code memory, generator polynomials well different constituent codes on studied parallel concatenated codes.
