Abstract

This paper presented a novel QC-LDPC codes optimization method,Diff-PEXIT algorithm.The simple recursive encoding structure of QC-LDPC codes is remained during the optimization process.Simulation results show that the BER performance of proposed QC-LDPC code is better than that of 802.16e code and Tam code.
