A METHOD OF TRANSMITTING USING PHASE SHIFT-BASED PRECODING AND AN APPARATUS FOR IMPLEMENTING THE SAME IN A WIRELESS COMMUNICATION SYSTEM

摘要

A data transmission method and a transmitter/receiver using a precoding matrix based on phase transition are provided to minimize interference between multi-users by maintaining the advantage of PARC(Per Antenna Rate Control) and reduce feedback overhead. A channel coding and modulating unit performs channel coding and the modulation independent in user data through an antenna by using feedback information from a reception terminal. A pre-coder determines phase transition base precoding matrix and precodes user data by using the determined phase transition base precoding matrices. The precoding matrices decision module determines the phase transition base precoding matrices by multiplexing the first matrices connected to the phase transition and the second matrices for making the first matrices become matrix.
