System and method for antenna selection
First Claim
1. In a transmitter having one or more RF chains and a plurality of transmit antennas capable of transmitting RF signal energy to a receiver, an antenna selection method comprising:
- connecting the one or more RF chains to an initial subset of the plurality of transmit antennas;
determining a bit error rate of the receiver associated with each transmit antenna within the initial subset of the plurality of transmit antenna;
comparing each bit error rate to a predefined threshold;
disconnecting, when one the bit error rate exceeds the predefined threshold, an associated transmit antenna within the initial subset of the plurality of transmit antennas from a first of the one or more RF chains; and
connecting one of the plurality of transmit antennas to the first of the one or more RF chains, the one of the plurality of transmit antennas not being included within the initial subset of the plurality of transmit antennas.

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.
