ABSTRACT:
Beamforming is provided for a wireless MIMO device by using antenna puncturing to reduce the number of transmit antennas that are used to transmit data for certain subcarriers. In a conventional approach, if N spatial streams are being used to provide spatial multiplexing, then N transmit antennas would be used to transmit for each subcarrier. In at least one embodiment of the invention, enhancements in channel capacity are achieved by using less than N transmit antennas for one or more subcarriers.
