LDPC-CPM(连续相位调制信号)

代码说明：

说明：  LDPC码是一种分组码,其校验矩阵只含有很少量非零元素。正是校验矩阵的这种稀疏性,保证了译码复杂度和最小码距都只随码长呈现线性增加(LDPC code is a block code, and its check matrix contains only a few non-zero elements. It is the sparsity of parity check matrix that ensures that decoding complexity and minimum code distance increase linearly with code length)
