Research on Fast Diversity and Multiplexing Selection Algorithm for Multi-Antenna Systems

The multi-antenna systems employ both diversity and spatial multiplexing, which have a trade off relationship. This thesis is analyzing linear receiver with multiple antenna system of spatial multiplexing, on the premise of providing large information transmission rate and capacity and transmission reliability, giving a quick selection algorithm based on the BER guidelines diversity multiplexing mode. The algorithm is selecting diversity multiplexed mode by less complicated multi-antenna systems, at the same time, sending a small amount of information back to the sender, to achieve the full advantage of multi-antenna systems diversity and multiplexing. This algorithm can make full use of diversity multiplexing MIMO systems, having better transmission performance and low computational complexity.
