摘要：In this paper, we study the convergence behaviour of a new SISO decoder that we have proposed recently in [1]. The exchange of extrinsic information is used to trace the decoding trajectory in the extrinsic information transfer Chart. That allows foreseeing the turbo cliff position. The influence of concatenated scheme as well as different constituent codes on the convergence behaviour is investigated for product and generalized serially and parallel concatenated codes. Simulation result shows that the thresholds obtained by EXIT chart and BER curves are almost the same.
