A wireless transceiver, comprising a transmitter, a receiver and a plurality of antennas, determines transmit phase relationship between at least two of antennas based on radio frequency (RF) signals received via the at least two antennas from one or more antennas of a base station. RF signals are transmitted via the at least two antennas utilizing the determined transmit phase relationship. The receiver is calibrated based on receiver performance determined from the received RF signals for subsequent reception of RF signals. The transmit phase relationship is dynamically adjusted based on the transmit RF measurements and the determined receiver performance. Transmit channel qualities are determined for each transmit antenna based on the transmit RF measurements and the dynamically adjusted transmit phase relationship. Transmit antennas are dynamically selected based on the adjusted transmit phase relationship, the characterized transmit channel qualities and the determined receiver performance for subsequent transmission to the base station. |
