A method and system for selective mode adaptation for transmitting data by spatial multiplexing applicable in communications systems with a transmit unit having multiple transmit antennas (18A-18N) or multiple transmit units and a receive unit having multiple receive antennas (34A-34N). A channel descriptor, such as channel matrix H or a channel matrix filter <i>H</i>, with has sub-descriptors correspondin g to the transmit antennas is determined and a quality parameter, such as signal-to-interference and noise ratio, signal-to-noise ratio or power level are chosen. The quality parameter is assigned a thereshold and the sub-descriptor or sub-descriptors whose quality parameters do not meet the threshold are identified and deactivated (40, 26). |
