Abstract
A receiver includes an antenna for a wireless communication with a transmitter and a signal processor to process a radio signal received via a radio channel. The receiver constructs a codebook including sets of beamforming weights for a plurality of directions. The beamforming weights are based on a first antenna array response matrix of a transmitter antenna array. The transmitter selects beamforming weights from the codebook to form a transmit/receive beam pointing in a selected direction. The receiver calculates one or more characteristic matrices based on a model of the transmitter antenna array, and constructs the codebook using a second antenna array response matrix and the one or more calculated characteristic matrices.
