Abstract:
A first network device including a first calibration module to generate training signals for each of a plurality of subcarriers. The training signals are transmitted from the first network device to a second network device via antennas of the first network device using the subcarriers. A first steering module receives a first matrix for each subcarrier, which includes channel state information for each of the training signals received by the second network device, from the second network device according to a transmission schedule and generates a steering matrix based on the first matrix. The transmission schedule is predetermined or is transmitted to the second network device prior to transmitting the training signals. A first control module adjusts, based on the steering matrix, first beamforming weights associated with the antennas to direct first radio frequency signals to be transmitted toward the second network device.
