Guangtongxin yanjiu, 2014 基于等差矩阵的性质特征,提出了一种QC-LDPC（准循环低密度奇偶校验）码的新颖构造方法。该构造方法易于有效编译码,具有良好的围长特性,可有效避免四环,使生成的码字不受短环的干扰,且在硬件实现方面可节省存储空间。仿真结果表明:当误码率达到10-7时,该构造方法造出的高码率QC-LDPC（3780,3542）码与ITU-T G.975中的RS（255,239）码相比,其净编码增益提高了约2.1dB,具有更好的纠错性能;与QC-LDPC（4221,3956）码相比,净编码增益提高了0.35dB。

Explicit construction of girth-eight QC-LDPC codes and its application in CRT method
Tongxin xuebao, 2012 For arbitrary code lengths of the form PL(P≥3L<sup>2</sup>/4+L-1),a new family of (4,L)-regular quasi-cyclic (QC) low-density parity-check (LDPC) codes was proposed explicitly with girth ight.Employing the new code as a component code in the ...
