Abstract
A noise canceller device for removing interference signals from other systems and improving communication quality of a desired signal is provided. The noise canceller device comprises a first calculation unit performing cross-correlation processing on interference signals received by sub-antennas, a first peak detection unit detecting peaks of the interference signals, a first information acquisition unit acquiring first interference signal information, a composition unit composing the interference signals, a second calculation unit performing correlation processing between a signal received by a main antenna and the composed interference signal, a second peak detection unit detecting a peak of the composed interference signal, a second information acquisition unit acquiring second interference signal information, an interference signal replica generation unit generating an interference signal replica, and a removal unit subtracting the interference signal replica from the received signal by the main-antenna.
