Concatenated QC-LDPC and SPC Codes for Turbo Decoding in Differentially Encoded System
Yu Zhao, Nebojša Stojanović, Fan Yu, D. Chang, Z. Xiao, Changsong Xie · 2013
A new class of codes is proposed for differentially encoded coherent systems. Regular Quasi Cyclic Low Density Parity Check codes concatenated with two-dimensional single parity check codes improved performance by 0.4 dB without complexity increase.
