The recently proposed extrinsic information transfer(EXIT) chart is a powerful yet simple method for optimizing irregular low-density parity-check (LDPC) codes.
最近提出的外部信息转移图是一种优化非正则LDPC码的简单高效方法。
Based on some characteristics of decoding and error-floors of low-density parity-check (LDPC) codes, an approach of adding vertical parity-check blocks to original LDPC blocks over GF (2) is proposed.
基于LDPC码在译码和差错平底区域的一些特殊性质，提出了一种为GF(2)域上的LDPC码已编码码字增加纵向校验码字的方法。
Low Density parity check (LDPC) codes are a kind of linear block codes approaching Shannon limit. They can be constructed either with spare parity-check matrix or with factor graphs.
LDPC码是一种可以接近香农限的线性分组码，可通过稀疏奇偶校验矩阵来构造，也可以用因子图来构成。
