FIG. 1 illustrates a wireless multiple-in-multiple-out (MIMO) communication system 100, which includes a first transceiver 102 with MT transmit (TX) antennas 104 and a second transceiver 106 with MR receive (Rx) antennas 108, forming an MR�MT. MIMO system. For the description below, the first transceiver 102 is designated as a “transmitter” because the transceiver 102 predominantly transmits signals to the transceiver 106, which predominantly receives signals and is designated as a “receiver”. Despite the designations, both “transmitter” 102 and “receiver” 106 may include a transmit section 110 and a receive section 112 and may transmit and receive data.
and multiply this value by the estimated transmitted signal vector In an embodiment, these computations may be performed using an orthogonal matrix triangularization (or “QR decomposition”) of the MR�MT, channel response matrix H, such that
