A method of maximizing a communication parameter, such as data capacity, signal quality or throughput of a channel between a transmit unit with M transmit antennas and a receive unit with N receive antennas and a communication system employing the method. The data is first processed to produce parallel spatial-multiplexed streams SMi, where i=1...k, which are converted or mapped to transmit signals TSp, where p=1...M, assigned for transmission from the M transmit antennas. Corresponding receive signals RSj, where j=1...N, are received by the N receive antennas of the receiver and used to assess a quality parameter, such as a statistical signal parameter or a parameter of the data. The quality parameter is used to adaptively adjust k as well as other parameters to transmit antennas such that the communication parameter of the channel is maximized. |
