Adaptive genetic algorithm assisted multi user detection for FD-MC-CDMA in various frequency selective fading channels

摘要

The main aim of multi-carrier code division multiple access (MC-CDMA) mobile communication systems are to overcome the multi-path fading influences as well as the near-far effect and to increase its capacity. Different types of optimal and suboptimal multi-user detection schemes have been proposed and analyzed in literature. Unfortunately, most of them share the drawback of requiring an efficient practical solution. In this paper propose adaptive genetic algorithm based novel multi user detection algorithm and compare its performance with existing multi user detection algorithms in various frequency selective fading channels. Simulation results confirmed that the proposed adaptive genetic algorithm assisted multi user detection algorithm performs better compared to the existing multi user detection algorithms.
