[Problem] To provide a noise canceller device capable of removing interference signals from other systems and improving the communication quality of a desired signal. [Solution] A noise canceller device performs cross-correlation processing on interference signals received by sub-antennas (12) by a first correlation value calculation unit (13), detects the peaks of the interference signals by a first peak detection unit (14), acquires interference signal information by a first interference signal information acquisition unit (15), synthesizes the interference signals by an interference signal synthesis unit (16), performs correlation processing on a signal received by a main antenna (11) and a synthesized interference signal by a second correlation value calculation unit (18), detects the peak of the synthesized interference signal by a second peak detection unit (19), acquires interference signal information by a second interference signal information acquisition unit (20), generates an interference signal replica by an interference signal replica generation unit (21), and subtracts the interference signal replica from the signal received by the main antenna (11) by an interference signal removal unit (23). |
