[Communication] ldpc_distr DL : 0: LDPC码是Low Density Parity-check Codes的缩写，一个长为N的LDPC码由它的校验矩阵H来定义，该矩阵的特点是其中的元素0特别多，1特别少——即所谓的“低密度”。一个参数为（N，i，j）的H表示该矩阵中每列有i个1，每行有j个1，矩阵大小为N×K，N代表码字长度，K代表校验子的个数。 -LDPC code is the ab. of Low Density Parity-check Codes. A Length N LDPC is defined by its H matrix. The matrix has many zeros and few ones. which called \"low density\". An H matrix has a parameter as (N,i,j) express that it is the matrix which has i s 1 in each column ,j s one in each row, the size of the matrix is N*K,the N is the code word length ,k is the number of the checks.
