A method includes determining weights corresponding to each of a plurality of antennas used to transmit data signals, each weight suitable to modify a corresponding one of the data signals prior to transmission using a corresponding one of the antennas; and transmitting information corresponding to at least one of the weights, the information allowing at least the at least one weight to be determined. Another method includes receiving information corresponding to at least one of a plurality of weights, the plurality of weights corresponding to a plurality of first antennas used to transmit first data signals, where each weight was used to modify a corresponding one of the first data signals prior to transmission using a corresponding one of the first antennas; using the received information, determining the plurality of weights corresponding to the plurality of first antennas; and using at least the plurality of weights; and decoding second data signals received using a plurality of second antennas to create at least one output signal.
