<p>Disclosed is an interference-cancelling repeating technique that has no signal distortion and can remove a feedback signal more precisely. According to the present invention, an interference-cancelling repeater comprises: a reception part that receives an analog signal; an A/D converter part that converts the analog signal received by the reception part into a digital signal; a channel filter part that allows only a desired band of the digital signal converted at the A/D converter part to pass through; a feedback signal removing part that removes a feedback signal included in the digital signal where only the desired band is allowed to pass through by the channel filter part; a D/A converter part that converts the digital signal, where the feedback signal is removed by the feedback signal removing part, into an analog signal; a control part that controls the channel filter part and the feedback signal removing part; and a transmission part that transmits the analog signal converted at the D/A converter part.</p> |
