Grassmannian beamforming
WebThis paper develops two new classes of beamforming algorithms that exploit the interframe correlations in the channel fading of a first-order autoregressive (AR1) dynamic fading model and introduces a novel successive beamforming (SBF) algorithm. Transmit beamforming has been widely adopted for wireless systems with multiple transmit antennas.
