Abstract: A plurality of received signals are received at a first communication device, the plurality of received signals corresponding to at least one training signal having been transmitted by a second communication device a plurality of times via a plurality of antennas by the second communication device applying a respective antenna weight vector from a plurality of different antenna weight vectors each time the at least one training signal is transmitted. The first communication device generates a transmitter antenna weight vector based on a mathematical combination of at least i) the plurality of received signals, ii) the antenna weight vectors applied by the second communication device when transmitting the at least one training signal the plurality of times, and iii) the at least one training signal. The first communication device transmits the transmitter antenna weight vector to the second communication device.

Abstract: A set of multiple training signals to be transmitted via multiple antennas over a communication channel are generated, and a different antenna weight vector (AWV) from a first set of AWVs is applied to each of the multiple training signals as the training signals are transmitted during a current iteration of a beamforming procedure. Feedback generated using the multiple training signals is received. A second set of AWVs to be used in a next iteration of the beamforming procedure is determined using the feedback.
