Signal Processing Performance analysis of PSO-based parallel interference canceller for MC-CDMA communication systems

This work analyses the performance of particle swarm optimisation (PSO) algorithm-based parallel interference cancellation (PIC) multiuser detectors exploited in multicarrier direct-sequence code-division multiple-access (MC-DS-CDMA) communication systems over frequency-selective fading channels. The PSO, which attempts to reduce the complexity in optimal detection caused by the greedy exhausted searching, achieves adequate sub-optimal multiuser detection in CDMA systems. Simulation results reveal that with a lower generation of Gn = 5, 10, the constant weight PIC (CWPIC) scheme outperform the conventional PIC (CPIC) particularly at heavy load. However, with higher generation Gn = 20 in PSO, the CPIC schemes contrarily outperform the CWPIC for all system loads. Copyright © 2008 John Wiley & Sons, Ltd.
