Abstract

A wireless transceiver includes a plurality of antennas. A plurality of signal recovery circuits generate a selected number of received signals from a first subset of the plurality of antennas, based on a control signal. A receiver section recovers an inbound data stream from the selected number of received signals. A plurality of transmitter sections generate a selected number of transmitted signals to a second subset of the plurality of antennas, based on the control signal, wherein the intersection between the first subset of the plurality of antennas and the second subset of the plurality of antennas is the null set for each value of the control signal.
