DATA TRANSFER METHOD USING PHASE-SHIFT BASED PRECODING AND TRANSMITTER IMPLEMENTING THE SAME

摘要

A method of transmitting data using phase-shift-based precoding in a multiple antenna system using a plurality of subcarriers is disclosed. More specifically, the method includes determining a phase-shift-based precoding matrix for transmitting the data by adjusting a transmission phase angle for each antenna, applying an offset for applying offset information fed back from a receiving terminal to the determined precoding matrix, and performing precoding by multiplying the offset applied precoding matrix by a symbol of each subcarrier.
