摘要: 该文着重研究了一种新的距离度量在以卷积码为分量码、MQAM调制的MLC/PDL系统中的应用。在Rayleigg衰落信道下通过计算机仿真,验证了此度量的有效性,并得到在此度量下设计多级码的准则。Abstract: A new distance metric for MLC/PDL (MultiLevel Coding/ Parallel Decoding of Levels) with MQAM constellation is proved to be applicable when punctured convolutional code is used as component code over Rayleigh fading channel. The efficiency has been demonstrated by detailed simulation results. The performance comparison between punctured convolutional code and block code under the same condition is also given.
