Scarlett, J and Martinez, A and Guillen I Fabregas, A (2014) Mismatched multi-letter successive decoding for the multiple-access channel. IEEE International Symposium on Information Theory - Proceedings. pp. 2539-2543. ISSN 2157-8095

This paper studies channel coding for the discrete memoryless multiple-access channel with a given decoding rule. A multi-letter successive decoding rule depending on an arbitrary non-negative function q(x1, x2, y) is considered, and an achievable rate region and error exponent are derived. The rate region is compared with that of the maximum-metric decoder which uses the function q(x1, x2, y), and a numerical example is given for which successive decoding yields a strictly higher sum rate for a given pair of input distributions. © 2014 IEEE.
