Offset Shuffle Networks(OSNs) interleave a-posterior probability messages in the Block row-layered decoder(BRLD) of QuasiCyclic Low-Density Parity-Check(QC-LDPC)***,OSNs usually consume a significant amount of computational resources and limit the clock frequency,particularly when the size of the Circulant Permutation Matrix(CPM)is *** simplify the architecture of the OSN,we propose a Simplified Offset Shuffle Network Block Progressive Edge-Growth(SOSNBPEG) algorithm to construct a class of QCLDPC *** SOSN-BPEG algorithm constrains the shift values of CPMs and the difference of the shift values in the same column by progressively appending check *** results indicate that the error performance of the SOSN-BPEG codes is the same as that of the codes in WiMAX and *** SOSNBPEG codes can reduce the complexity of the OSNs by up to 54.3%,and can improve the maximum frequency by up to 21.7%for various code lengths and rates.
