Techniques for transformation codebook antenna beamforming in OFDM wireless communication system
Abstract:
Methods for a transmitter station and a receiver station to perform beamforming in a wireless communication system, and a transmitter station and a receiver station to perform the corresponding method, are provided. The method for the transmitter station to perform beamforming in the wireless communication system includes estimating and tracking a long-term averaged and normalized channel correlation matrix between the transmitter station and a receiver station, determining beamforming coefficients based on the tracked long-term averaged and normalized channel correlation matrix, and communicating with the receiver station using the determined beamforming coefficients, wherein the receiver station also estimates and tracks the long term averaged and normalized channel correlation matrix, and determines beamforming coefficients based on the tracked long-term averaged and normalized channel correlation matrix.
