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.
