ABSTRACT:
A wireless data processing system uses a selectively enabled multi-antenna processor to demodulate N separate data signals from M separate antennas simultaneously. The multi-antenna processor is adapted to respond to changing channel conditions between two access points, so that it selectively kicks in if there is noise, interference, frequency fading, a need for an enhanced data rate, a need for an increased operating range, etc.
