Firstly, the M-ary modulated Min-Sum algorithm which based on Maximum Liklihood is provided, however, can not be applied to actual decoding due to its complexity. By applying the so called Generalized Distributive Law, we simplified the Min-Sum decoding for M-ary modulated LDPC codes based on Maximum Likelihood, and obtained what we called Enhanced Min-Sum algorithm.
