摘要：

An approach for constructing a class of (3, k)-regular quasi-cyclic low-density parity-check (QC-LDPC) codes is proposed, which is based on combinatorial objects termed difference sequences. By an efficient algorithm for searching good difference sequences, codes in this class have girth at least eight. Simulation results show that the codes slightly outperform the counterpart PEG codes and have better performance than the corresponding MacKay codes and array codes.
