Abstract:
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.
