Abstract
A binning-based transmit beamforming for wireless communication systems includes determining a time correlation and a frequency correlation of a beamforming vector estimated from a previous transmission on a current hopping channel and one or more neighboring channels using one or more binning architectures that exploit channel correlation in both frequency and time dimensions. These binning architectures include global binning, local binning, and adaptive version of global and local binning. The subject system determines one or more beamforming weights for the current hoping channel according to the binning architecture, and provides, for transmission, a signal using transmit beamforming based on the one or more beamforming weights.
