Receive Antenna Diversity and Subset Selection in MIMO Communication Systems

Abstract — The performance of Multiple-input Multiple-output (MIMO) systems can be improved by employing a larger number of antennas than actually used or selected subset of antennas. Most of the existing antenna selection algorithms assume perfect channel knowledge and optimize criteria such as Shannon’s capacity on bit error rates. The proposed work examines Antenna diversity and optimal / sub optimal receive strategy in antenna selection. The numerical results for BER, Information capacity with SNR are obtained using mat la
