Joint Power Control and Multiuser Detection for MIMO Systems
In this paper, a joint iterative power control and parallel interference cancellation (PIC) scheme is proposed for turbo coded uplink DS-CDMA systems to suppress the multiple access interference (MAI) from co-channel users and interantenna interference (IAI) from adjacent antennas of each user. Simulation results show that the proposed scheme could compensate for some channel fading effect through power control, and improve the accuracy of the soft estimates from the turbo decoder to help with the reconstruction of the interference signals during the PIC processing, therefore, provides a significant reduction in the bit error rate (BER) compared to that of no power control.
