Abstract :
In this paper, we propose a sum rate maximizing ordering method for hard decision successive interference cancellation receiver of MIMO-OFDM systems. Compared with conventional ordering methods developed for open loop MIMO systems, the proposed scheme shows considerable improvement in throughput capacity. We propose two simplified methods with considerable complexity reduction and negligible performance degradation.
