Combined switching and power control for diversity and multiplexing in MIMO systems with cochannel interference
Diversity and multiplexing can relax the throughput limitations caused by the interference and the frequency-selective fading channel, respectively. An algorithm that uses the throughput as the selection criterion for switching between diversity and multiplexing is thus proposed in this paper. Owing to the throughput-based switching, the proposed algorithm can always get the largest throughput between diversity and multiplexing. In addition, the power control procedures for diversity and multiplexing are also proposed to further enhance the throughput. (C) 2008 Elsevier B.V. All rights reserved.
