Abstract
A method for selecting a precoder from a codebook for a channel matrix H and an apparatus. The method includes determining, by a processor, a reference precoder V for the channel H and a phase rotation for V; for all codewords W from a codebook, determining, by the processor, phase rotations for W and phase distances based on differences between phases of elements of V and W; and selecting, by the processor, the codeword W with a minimum phase distance, wherein H has a size of N×N, Nis a number of receive antennas, Nis a number of transmit antennas, V has a size of N×L, and L is a number of data layers transmitted simultaneously.
