Abstract
A method of transmitting data using a phase shift-based precoding in a multiple antenna system using a plurality of subcarriers is disclosed. More specifically, the method includes determining a diagonal matrix to provide different phase angles to each of the plurality of antennas as a part of a phase shift-based precoding matrix, selecting a unitary matrix from a first codebook as the part of a phase shift-based precoding matrix, and performing precoding to symbols associated with subcarriers based on the diagonal matrix and the unitary matrix.
