【Abstract】 A multiuser detection based on particle swarm optimization (MPSO-MUD) is proposed.The optimum multiuser detection system model and the main idea of PSO are introduced.Numerical results have shown that in aspect of bit-error rate and "near-far" resistance,the MPSO-MUD is better than the conventional detection (CD) and PSO-MUD.更多还原
