In a wireless communication system the receiver includes a first plurality of receive chains (11,12,13) and a second plurality of antennas (1,2,3,4,5,6). Each receive chain is selectively connectable to selected antennas. The antennas are selected based on criteria obtained from a received RF signal to produce an antenna configuration connected to the receive chains to reduce RF fading at the receiver. An electronic switch (sw1,sw2,sw3) connects the antennas to the receive chains. The receiver is programmed to determine which antenna should be connecte to each receive chain by the switch by measuring characteristics of the received signal for each allowed antenna configuration and selecting the best antenna configuration. Transmitters (27,28,29) may be similarly configured. |
