a)Refer to the LDPC presentation slides provided, and use the input data provided below to decode the codeword Repeat a) with new matrix H, codeword and σ^2 given below-a) Refer to the LDPC presentation slides provided, and use the input data provi

生成一个规则LDPC码的教研矩阵H,其行数(越大越好)为列数的一半-Generate a regular LDPC code research matrix H, the adults number (bigger is better) for half the number of columns

LDPC码的校验矩阵与生成矩阵互换，可以用来对LDPC码的H矩阵和G矩阵进行变换，采用了C语言的写法，简单明了。
