| 1. A method for processing signals in a communication system, the method comprising:
generating models for a received plurality of spatially multiplexed communication signals for multiple channels from a plurality
of transmit antennas;
maximizing a calculated signal to noise ratio (SNR) of each of said multiple channels based on said generated models; and
adjusting a phase and an amplitude of at least a portion of said received plurality of spatially multiplexed communication
signals based on a generated plurality of amplitude and phase correction weights determined from said maximizing.
