A MIMO-OFDM SYSTEM USING EIGENBEAMFORMING TECHNOLOGY AND EIGENBEAMFORMING METHOD IN THE SAME

摘要

The present invention is to reduce the short-term feedback information amount for the application of specific beamforming technology, in particular, an OFDM system relates to a MIMO-OFDM system according to the DL-specific beamforming (Eigenbeamforming).; In accordance with the present invention, adjacent ones of the total K sub-carriers Tie the subcarriers as a group Divided into two groups, select the same eigenvectors to each group. In this way, the number of bits of the entire short-term feedback information according to the present invention Been
