Patent ID: 8090329

Claim:
An antenna system comprising: a plurality of antennas; a switch matrix in communication with the plurality of antennas and adapted to couple selected antennas to a plurality of switch outputs; a radio module in communication with a first switch output and adapted to receive orthogonal frequency division multiplexing (OFDM) radio frequency signals having a plurality of frequency bins; a measurement module in communication with the radio module, and adapted to measure a degree of correlation of an amble in a received signal to a known amble; and a control module adapted to control selection of which of the plurality of antennas is coupled to the first switch output, wherein during a selection phase the control module selectively couples one desired antenna at a time to the first switch output and receives the measured degree of correlation of the radio frequency signal received by the selected antenna, the control module continues selecting and receiving measurements from a desired number of the plurality of antennas one at a time, then the control module combines the measurements from combinations of the antennas and determines a desired combination of antennas for simultaneous use during an operational phase, wherein the desired combination of antennas has preferred performance characteristics over individual antennas that make up the desired combination and wherein the desired combination of antennas provides the flattest response across all of the bins of the OFDM radio frequency signal.
