    摘要: A MIMO beamforming method comprises receiving at a base station information regarding a difference between an ideal beamforming matrix and an averaged beamforming direction, using the information to construct a beamforming matrix at the base station, and performing a beamforming operation using the reconstructed beamforming matrix. Alternatively, the method comprises computing at a subscriber station an averaged beamforming direction, computing at the subscriber station a quantization index corresponding to a differential matrix in a differential codebook, and transmitting the quantization index across a wireless channel of the wireless network. The differential codebook may be constructed by identifying a codebook center and transforming a predefined codebook that is stored in a memory of a component of the wireless network.
