PHASE SHIFT BASED PRECODING METHOD AND TRANSCEIVER SUPPORTING THE SAME

摘要

A phase shift-based precoding method and a transceiver for supporting the same are provided to extend easily a matrix for performing a pre-coding process based on phase shift according to the number of antennas. A modulation symbol acquiring process is performed to acquire at least one modulated symbol by modulating a transmission signal. A phase shift pre-coding process is performed to precode at least one modulated symbol in a phase shift pre-coding manner. A transmission process is performed to transmit the precoded symbol by using a multi-antenna. The phase shift-based precoding process is performed by using a unitary matrix and a diagonal matrix for phase shift. The diagonal matrix for phase shift is determined on the basis a spatial multiplexing rate.
