Abstract

Differential encoded LDPC (DE-LDPC) coded systems with multiple symbol differential detection (MSDD) scheme can avoid good estimation of channel state information and compensate performance degradation of differential detection. In this paper, LDPC codes optimization for the DE-LDPC coded systems with MSDD is studied. Simulation results show that the optimized LDPC codes perform much better than the regular LDPC codes for the DE-LDPC coded systems with MSDD.

具有多符号差分检测的LDPC差分编码系统的LDPC码优化

采用多符号差分检测(MSDD)方案的差分编码LDPC (DE-LDPC)编码系统可以避免对信道状态信息的良好估计，补偿差分检测的性能下降。本文研究了带MSDD的DE-LDPC编码系统的LDPC码优化问题。仿真结果表明，对于带有MSDD的DE-LDPC编码系统，优化后的LDPC码的性能明显优于常规LDPC码。
