Abstract

In this paper, we propose a forcing mutation scheme from GA to perform a forcing mutation evolutionary multiuser detector (FME-MUD) and to largely reduce computational complexity. Simulation results show that with a few generations G_n=6, the proposed FME-MUD scheme outperforms the conventional genetic algorithm based multiuser detector (GA-MUD) especially at heavy system load.
