An interference cancellation relay device, comprising:
- an interference cancellation unit cancelling an interference signal from an input signal and outputting the input signal from which the interference signal is cancelled;
- 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,
- wherein the gain control unit includes:
- a measurement unit detecting a reference signal from the output signal of the interference cancellation unit and measuring an intensity of the reference signal;
- and
- a control unit controlling the gain of the output signal of the interference cancellation unit by using the intensity of the reference signal, and
- wherein the control unit includes:
- a comparison unit comparing the intensity of the reference signal with a predetermined reference intensity;
- and
- a control unit controlling the gain of the output signal of the interference cancellation unit according to a result of comparing the intensity of the reference signal and the reference intensity.
An interference cancellation relay device, comprising:
- a first gain control unit controlling a gain of an input signal;
