Iterative Decoding Algorithm and Its Performance ofTurbo Codes on the Asymmetric Z-Channel[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 2010,49(1):29-33.DOI:
The asymmetric Zchannel is a discrete memoryless channel with one of the input symbols transmitted with noise. The maximum a posterior probability (MAP) decoding algorithm was analyzed
and a modified decoding algorithm on the asymmetric Zchannel was deduced. Based on the algorithm
simulations on the performance of turbo codes have been carried out
and the key issues of simulations are discussed. The simulation results show that turbo codes can get excellent bit error rate performance on the asymmetric Zchannel with our proposed decoding algorithm.
