Abstract

Multiuser detectors for CDMA system that use the successive interference cancellation (SIC) and parallel interference cancellation (PIC) techniques have been studied separately in the past. In this paper, we propose two new multiuser detectors which are the hybrid between the SIC and PIC. Simulation results show these proposed detectors outperform the conventional detector and achieve near single-user performance in both ideal and no power control systems that we have considered. In addition, we also present a generalised framework for convergence analysis of the PIC scheme.
