PHASE SHIFT BASED PRECODING METHOD AND TRANSCEIVER SUPPORTING THE SAME

摘要

A phase-shift based pre-coding method and a transceiver supporting the same are provided to simplify the transceiver and maintain advantages of a phase-shift diversity scheme. A pre-coding matrix is selected, based on feedback information transmitted from a receiving terminal, from a code book having a feature in that a row of at least one pre-coding matrix for a predetermined multiplexing rate is contained in row vectors of the pre-coding matrix for a multiplexing rate higher than the predetermined multiplexing rate. A signal to be transmitted is subjected to pre-coding by using the selected pre-coding matrix, and then the pre-coded signal is transmitted to the receiving terminal.
