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 transmitter module generates a transmit signal to a selected one of the plurality of antennas, based on the control signal. The intersection between the first subset of the plurality of antennas and the selected one of the plurality of antennas is the null set for each value of the control signal. The control signals can be generated in multiple different operational modes including, for instance, a cyclic modes and a fixed mode of operation.
