PROBLEM TO BE SOLVED: To provide a radio repeater avoiding or reducing a DC offset voltage caused by unwanted waves even when the unwanted waves enter from a transmission antenna to a reception antenna. SOLUTION: A relay station 1 includes: a first antenna 2; a second antenna 3; a signal processing part 4 for generating transmission signals SB to be transmitted from the second antenna 3 on the basis of reception signals SA received by the first antenna 2; and a correction processing part 5 for correcting second signals processed by the signal processing part 4 at a second point of time when a predetermined time elapses from a first point of time, on the basis of the signal value of first signals SC processed by the signal processing part 4 at the first point of time, to correct the DC offset voltage generated in the reception signals SA when the first antenna 2 receives the transmission signals SB transmitted from the second antenna 3.
