Abstract
Certain aspects of the method may comprise generating models for a received plurality of spatially multiplexed communication signals for multiple channels from a plurality of transmit antennas. A calculated signal to noise ratio (SNR) of each multiple channel may be maximized based on the generated models. A phase and an amplitude of at least a portion of the received plurality of spatially multiplexed communication signals may be adjusted based on a plurality of amplitude and phase correction weights determined from the maximized SNR.
