ldpc_distr
- 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 L
rs_eedec_euc
- The Reed-Somolon code is specified by the finite field, the length (length <= 2^m-1), the number of redundant symbols (length-k), and the initial zero of the code, init_zero, such that the zeros are: init_zer
