A MAP algorithm for decoding maximum transition run (MTR) codes, using the soft-decision approach, is presented in this paper. The algorithm is based on the Bayesian algorithm, and computes a posteriori log-likelihood ratio (LLR) for output bits, using codewords of the MTR code. The log MAP and maxlog MAP version of the algorithm have been developed… (More)
