Abstract: Provided is an interference cancellation relay device. The interference cancellation relay device includes: an interference cancellation unit cancelling an interference signal from an input signal and outputting the input signal from which the interference signal is removed; a gain control unit controlling a gain of an output signal of the interference cancellation unit; and a pre-distortion unit distorting the output signal of the interference cancellation unit, of which the gain is controlled by the gain control unit.
