LDPC codes optimization for differential encoded LDPC coded systems with multiple symbol differential detection
Yang Yu, Ziyan Jia, Weige Tao, Shiliang Dong · 2016
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.
