Abstract :
In this study a hybrid approach that employs a genetic algorithm (GA) and a multi-stage detector (MSD) for multi-user detection problems 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
