摘要：A method and system for selective mode adaptation for transmitting data by spatial multiplexing applicable in communications systems with a transmit unit (12) having multiple transmit antennas (18) or multiple transmit units (204,206) and a receive unit (14) having multiple receive antennas (34). A channel descriptor (22), such as channel matrix H or a channel matrix filter H, with has sub-descriptors corresponding to the transmit antennas (18) 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 threshold and the sub-descriptor or sub-descriptors whose quality parameters do not meet the threshold are identified and deactivated.
