ABSTRACT:
Systems and methods that provide antenna selection in multi-antenna-element communication systems are provided. In one embodiment, a system that selects N antenna elements in an M-antenna-element transmitter or an M-antenna-element receiver, in which N is less than M, may include, for example, M antenna elements in the M-antenna-element transmitter or the M-antenna-element receiver; N RF chains; and a switch coupled to the N RF chains. The M-antenna-element receiver may determine a bit error rate for each possible N antenna element subset of the M antenna elements. The M-antenna-element receiver may determine the particular N antenna element subset with a lowest bit error rate. In response to the determination of the particular N antenna element subset with the lowest bit error rate, the switch may couple the N RF chains to the particular N antenna element subset with the lowest bit error rate.
