- Theory , 2002 , 48 : 1570 - 1579 . 5 kou y , lin s , fossorier m p c . low - density parity - check codes based on finite geometries : a rediscovery and new results . ieee trans
Schwartz和vardy在2005年得到以下结果：任给校验矩阵h0 ，一定可以通过增加冗余行得到新的校验矩阵h使得停止距离s h达到上界d 。 - And some other construction methods based on finite geometry , graph theory and group theory are also depicted . an algebraic construction method for ldpc codes with 8 - girth is proposed based on complete residue system . simulation results show that these codes can achieve better performance than randomly constructed regular ldpc codes over awgn channel
最后，在分析、研究现有构造方法的基础上，基于代数中的完全剩余系，作者提出了一种代数构造方法，使得ldpc码对应因子图上的围长为8 ，并采用计算机对其性能进行了仿真，结果表明该码能够取得比较理想的译码性能。
