Method and apparatus for feeding back and constructing correlation matrix in multi-input multi-output systems
The present invention provides a method for feeding back a correlation matrix in a multi-input multi-output system, comprising: constructing codebooks for the correlation matrix based on a conjugation nature of the correlation matrix and based on a predetermined relationship between diagonal elements and off-diagonal elements in the correlation matrix; selecting a codeword from the constructed codebook; and feeding back a corresponding index of the selected codeword in the codebook. Through the present invention, the throughput of the multi-input multi-output system can be enhanced, while reducing the encoder complexity or transfer load.
