Low-complexity likelihood probability derivation algorithm for non-binary LDPC-coded modulation system

The derivation of likelihood probabilities which are sent into the decoder in many LDPC-coded modulation systems is a challenging task especially when high-order modulations are used.This is because likelihood probabilities are usually complicated functions of the channel output and their calculatio...
