摘要

循环耦合准循环LDPC (CC-QC-LDPC)分组码具有优异的误码性能和极低的误码下限。在本文中，我们提出了两种新的CC-QC-LDPC分组码，可以实现更大的周长。给出了用该机制构造的CC-QC-LDPC码的误差性能。结果表明，在码长相似的情况下，新编码比原来的CC-QC-LDPC编码性能好0.3 ~ 0.35 dB，误码率为10-12。

Novel types of cyclically-coupled quasi-cyclic LDPC block codes

Cyclically-coupled quasi-cyclic LDPC (CC-QC-LDPC) block codes have been shown to achieve outstanding bit error performance with extremely low error floor. In this paper, we propose two new types of CC-QC-LDPC block codes which can achieve a larger girth. We present the error performance of the CC-QC-LDPC codes constructed by the new mechanism. We show that with similar codelengths, the new codes outperform the original CC-QC-LDPC codes by 0 3 to 0 35 dB at a bit error rate of 10-12.
