MIMO partial parallel interference cancellation for space time block coded MIMO-CDMA system

We propose a simple and reliable MAI (multiple access interference) cancellation scheme for MIMO-CDMA system using STBC (space time block code). Base on the fact that the performance of the PIC (parallel interference cancellation) depends on the initial data decisions, the accurate MAI estimation, we search the scheme of MP-PIC (MIMO partial PIC) to improve performance in MIMO-CDMA system. The MAI estimation method in the proposed scheme can be achieved by removing the strong interferers from received signals. It is shown that the proposed MP-PIC not only achieves similar performance of conventional PIC, but also reduces by a half of the complexity
