Hypotheses Control-Based Strategies for the Simplification of Bayesian Multiuser Detectors

This paper deals with the development of several simplification strategies, which can be applied to those communication problems analyzed using the Bayesian formulation. Specifically, we will focus our interest on the multiuser detection problem in wireless DS/CDMA environments, where the complexity of the theoretical algorithm grows exponentially with the number of active users as well as with the number of symbols received. The implementation of these algorithms is, most of the times, an unfeasible task and reduced-complexity suboptimal algorithms must then be developed. This paper constitutes a continuation of previous work of the author on Bayesian single- and multi-user detectors for wireless communications
