The present invention provides a method for removing self-interference by a transmitter side in a wireless access system that supports a full duplex radio (FDR) scheme, according to one embodiment of the present invention, comprises the method comprising the steps of: transmitting two transmission signals, using two transmission antennas; receiving two reception signals, using two reception antennas; estimating a self-interference channel; and removing interference signals in consideration of the estimated self-interference channel among the received signals. In the method, the interference signals are the transmission signals which are input into the two reception antennas, the transmission signals and the reception signals are simultaneously transmitted and received through a resource area configured by the same time and frequency, and the two transmission antennas and the two reception antennas may be disposed on the transmitter side in a diamond shape. |
