Patent ID: 7706457

Claim:
A method of receiving multicarrier beamformed signals comprising: generating decimated beamforming matrices for beamforming groups of two or more subcarriers based on a decimation factor, wherein a number of subcarriers in a beamforming group is based on a receive data rate; and receiving signals from a multicarrier transmitter at the receive data rate, the decimated beamforming matrices being applied to the subcarriers of the signals prior to transmission, wherein for higher receive data rates the decimation factor is decreased to decrease the number of subcarriers in each beamforming group, wherein for lower receive data rates the decimation factor is increased to increase the number of subcarriers in each beamforming group, wherein for a communication channel comprising a predetermined number of subcarriers, a greater number of decimated beamforming matrices are generated for higher-receive data rates and a lesser number of decimated beamforming matrices are generated for lower-receive data rates.
