Abstract:
The present invention discloses a method for generating beamformed multiple-input-multiple-output (MIMO) channels. The method comprises receiving by a base station (BS) a first plurality of receiving signals transmitted from a first antenna on a mobile station (MS), receiving by the BS a second plurality of receiving signals transmitted from a second antenna on the MS, nulling out a first predetermined percentage of the second plurality of receiving signals to generate a third plurality of receiving signals, calculating a first beamforming weighting vector corresponding to the first antenna on the MS using the first and third pluralities of receiving signals and creating a first beamformed MIMO channel from the BS to the first antenna on the MS using the first beamforming weighting vector.
