On the design, selection algorithm and performance analysis of limited feedback transmit beamforming
13 years 7 months ago
Multiple-input multiple-output (MIMO) systems achieve significant diversity and array gains by using transmit beamforming. When complete channel state information (CSI) is not avai...
