摘要：

In this paper, a receiver algorithm for uplink multiuser orthogonal frequency-division multiplexing (OFDM) with a receiver-diversity system is proposed. The receiver uses a simple multiuser generalization of the maximum a posteriori probability (MAP) selection diversity combining followed by parallel interference cancellation with least-squares projection (PIC-LSP) for multiuser detection. Compared with the near-maximal-ratio-combining (near-MRC) scheme, simulation results show that the proposed approach achieves very good performance and has much lower complexity.
