摘要：
In this work, a novel optimum multiuser detector (MUD) based on a particle swarm algorithm is presented. The proposed algorithm outperforms the matched filter and the decorrelator multiuser detectors. Moreover, the performance under near-far scenario, the system capacity, and the computational complexity of the proposed detector are also investigated.
