    摘要: A rotating reference codebook used in a multiple input multiple output (MIMO) communication system is provided. The reference codebook includes codewords from a discrete Fourier transform (DFT) codebook. A base station and a terminal may calculate a rotation matrix based on a previous preferred codeword and a random codeword among codewords included in the DFT codebook. A reference codebook may be rotated using the rotation matrix and may be transformed to a new codebook. The reference codebook may include codewords of a polar cap codebook and the codewords of the DFT codebook. Even though the codewords of the DFT codebook are rotated, the codewords of the DFT codebook may remain in the new codebook as elements of the DFT codebook.

    摘要: A multiple input multiple output (MIMO) communication system using an explicit feedback is provided. In the MIMO communication system using the explicit feedback, a receiver may generate an explicit feedback vector by calculating an explicit channel matrix, and by vectorizing the explicit channel matrix or an explicit channel matrix processed using a predefined function. Feedback information generated based on the explicit feedback vector may be provided to a transmitter. The transmitter may reconfigure the explicit channel matrix or the processed explicit channel matrix based on the feedback information. The transmitter and the receiver may share the explicit channel matrix or the processed explicit channel matrix using an adaptively transformed codebook.
