Abstract :
In this paper, we investigate throughput performance of downlink multi-antenna transmission schemes exploiting multiuser diversity. The asymptotic analysis is performed based on the extreme value theory. From this analysis, it is demonstrated that the multiuser spatial multiplexing known as the asymptotically optimal transmission scheme is no longer optimal in highly correlated multiple antenna channels
