Application of a genetic algorithm to multi-stage detection in CDMA systems

Abstract

In this study, a hybrid approach that employs a generic algorithm (GA) and a Multi-stage detector (MSD) for multi-user detection problem in Code Division Multiple Access (CDMA) communications system is proposed. Using this approach, a genetic algorithm is used as the first stage of MSD to provide a good initial point for successive stages of MSD. Simulation results for the synchronous case are provided to show that the approach is promising.
