引入PEG（Progressive-edge-growth）算法来构造适合线性时间编码的LDPC校验矩阵，译码时采用简化最小和Min-Sum译码算法实现简化译码．仿真结果表明，该方法能够构造适合LDPC码的线性时间编码的下三角校验矩阵日，并且用此方法构造的LDPC码性能非常接近原来PEG算法构造的LDPC码．同时通过采用最小和Min-Sum算法降低译码复杂度．,The introduction of PEG (Progressive-edge-growth) algorithm to const

LDPC 码二进制规则码生成矩阵2048*4096，效果很理想-LDPC code rules binary code generated matrix 2048* 4096, the effect is very satisfactory

Adaptive Quantization in Min-Sum based Irregular LDPC Decoder. this is a good method for LDPC decoder
