METHOD TO DO PRE-CORDING BASED ON PHASE SHIFT AND DEVICE FOR ITS SUPPORT IN WIRELESS COMMUNICATION SYSTEM Russian patent published in 2011 - IPC H04L27/32 H04B7/04 H04L27/18 

FIELD: information technologies.

SUBSTANCE: method includes detection of a diagonal matrix to provide different phase angles to each of multiple antennas as a part of matrix of pre-coding based on phase shift, selection of a unitary matrix from the first coding table as a part of matrix of pre-coding based on phase shift; and pre-coding relative to symbols associated with subcarriers, on the basis of a diagonal matrix and a unitary matrix.

EFFECT: improved functioning of communication.
