METHOD, TRANSMITTER AND RECEIVER FOR BEAMFORMING |
摘要 |
Embodiments of the invention provide a method for beamforming based on Grassmannian predictive coding (GPC) in a MIMO system. The method may comprise steps of: estimating present channel direction information (CDI) according to a received signal; predicting future CDI based on the present CDI and at least one of previous CDIs; predicting future codebook based on present codebook and at least one of previous codebooks; selecting a codeword from the future codebook based on the future CSI; and feeding back an index of the selected codeword to the transmitter.
