  • Codebook generating method and apparatus for generating a codebook for multi-polarized multiple-input multiple-output (MIMO) systems
    Patent number: 8611463
    Abstract: A terminal and method for generating a codebook for a multiple-input multiple-output (MIMO) system is provided. The codebook generation includes: assigning a single-polarized precoding matrix to diagonal blocks among a plurality of blocks arranged in a block diagonal format in which a number of diagonal blocks corresponds to a number of polarization directions of transmitting antennas; and assigning a zero matrix to remaining blocks excluding the diagonal blocks.
    Type: Grant
