Abstract
Provided is a multiple-input multiple-output (MIMO) communication system that may provide a plurality of feedback modes. A receiver may feed back, to a transmitter, a base codeword indicator indicating one of base codewords included in the base codebook, a differential codeword indicator indicating one of differential codewords included in the differential codebook, and/or a correlation codeword indicator indicating one of correlation codewords included in the correlation codebook. The transmitter may generate a precoding matrix using at least one of the base codeword indicator, the differential codeword indicator, and the correlation codeword indicator.
