<p>A method of beamforming comprising: transmitting a plurality of signals from a transmitter, each signal being transmitted over a plurality of subcarriers, each subcarrier having a weight factor associated therewith; receiving the plurality of signals at a receiver; and for each signal: analyzing the received signal in order to obtain its phase profile, the phase profile comprising the phase for each subcarrier; calculating a plurality of parameters representing the phase profile, the plurality of parameters being less in number than the number of subcarriers; sending the plurality of parameters back to the transmitter; reconstructing a representation of the phase profile at the transmitter using the plurality of parameters; and adjusting the weight factor of each subcarrier using the reconstructed representation of the phase profile, wherein further signals are transmitted by the transmitter using the adjusted weight factors.</p> |
