METHOD TO DO PRE-CORDING BASED ON PHASE SHIFT AND DEVICE FOR ITS SUPPORT IN WIRELESS COMMUNICATION SYSTEM

摘要

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. ^ 14 cl, 8 dwg, 6 tbl
