Abstract
Abstract — An adaptive multistage parallel interference cancellation technique based on a partial interference cancellation (IC) approach [1] was proposed in [2] for multipath fading channels. In this paper, the proposed technique is applied to develop a receiver structure in an AWGN environment. Unlike the scheme in [1], the weighting factors in this proposed scheme are derived by minimizing the meansquare error between the received signal and its estimate through an LMS algorithm. Neither training sequence nor pilot signal is needed. The complexity of the proposed adaptive multistage PIC structure is much lower than that of linear multiuser detectors. Simulation results show superior performance of the proposed receiver structure over an AWGN channel and in various conditions. I.
