Abstract
A method for an apparatus that supports full-duplex radio (FDR) communication controlling a self-interference duplication signal for removing self-interference comprises the steps of: transmitting two reference signals; and measuring the power of the two reference signals that arrive as self-interference signals; and a self-interference duplication generation unit for duplicating and generating a self-interference signal including three elements controlling two elements of the three elements based on the measured power of a first reference signal of the two reference signals, and controlling the remaining element based on the measured power of a second reference signal, wherein the three elements comprise a time delayer, a phase shifter and an attenuator, and the two reference signals are orthogonal to each other.
