Title
Low-Complexity Channel-Likelihood Estimation for Non-Binary Codes and QAM
Abstract
An approximate channel-likelihood estimation algorithm is introduced for non-binary coded, square quadrature-amplitude-modulated systems. It is shown that the proposed approximation greatly simplifies the calculation of channel-likelihoods and yet provides results close to those based on exact calculations for non-binary low-density parity-check codes over the additive white Gaussian noise channel.
