Abstract :
In this paper, a receiver algorithm for OFDM with receiver diversity is proposed. The proposed receiver uses a new multi-user generalization of the maximum a posteriori probability (MAP) selection diversity combining followed by successive interference cancellation with least-square projection for multi-user detection. Simulation results show that the proposed approach achieves near-maximal-ratio-combining performance with much lower complexity.
