Abstract
A terminal and a base station using an adaptive codebook for a polarization are provided. The terminal includes a rotation matrix generator to generate rotation matrices corresponding to a cross polarization discrimination value (XPD) of a transmission signal and a codebook generator to generate a codebook including result matrices that are generated based on pre-stored block diagonal matrices and the rotation matrices.
