Patent ID: 7822140

Claim:
A communication method for use by a wireless transceiver, comprising: demultiplexing, by a demultiplexer, an input signal into a first plurality of demultiplexed signals; weighting and combining, by a first circuit configured to weight and combine in the baseband domain, said first plurality of demultiplexed signals prior to upconverting; upconverting, by upconverters, said first plurality of demultiplexed signals into a first plurality of upconverted signals; dividing, by dividers, said first plurality of upconverted signals into a second plurality of divided signals; weighting, by a second circuit configured to weight, said second plurality of divided signals to form a second plurality of weighted signals, wherein weights used by the second circuitry to weight said second plurality of divided signals are obtained from an eigenvector corresponding to a largest eigenvalue of a cross-correlation matrix; combining, by a combiner, ones of said second plurality of weighted signals to form a third plurality of combined signals; and transmitting said third plurality of combined signals over a plurality of antennas.
