Summary:1212A wireless receiver for receiving signals from a transmitter. The transmitter comprises a plurality of transmit antennas (TAT′, TAT′) for transmitting the signals, which comprise respective independent streams of symbols. Additionally, interference occurs between the respective streams. The receiver comprises a plurality of receive antennas (RAT′, RAT′) for receiving the signals as influenced by a channel effect between the receiver and the transmitter. The receiver also comprises circuitry for multiplying the signals times a conjugate transpose of an estimate of the channel effect and times a conjugate transpose of a linear basis transformation matrix. The receiver also comprises circuitry for selecting the linear basis transformation matrix from a finite set of linear basis transformation matrices. Lastly, the receiver comprises circuitry for removing the interference between the respective streams.
