Abstract :
This letter proposes a receiver algorithm for orthogonal frequency division multiplexing (OFDM) with receiver diversity that uses a new multiuser generalization of the maximum a posteriori probability (MAP) selection diversity combining followed by successive interference cancellation with least-square projection for multiuser detection. Simulation results show that the proposed approach achieves near-maximal-ratio-combining performance at a much lower complexity
