Abstract
Receiver sensitivity deterioration in a wireless receiver section due to radio noise is reduced. A noise acquisition section acquires noise generated from a noise source. A noise adjustment section obtains a noise canceling signal by adjusting a phase and a gain of the noise acquired by the noise acquisition section. Subsequently, an antenna section transmits the noise canceling signal obtained by the noise adjustment section. For example, the noise acquisition section acquires the noise generated from the noise source by allowing the antenna section to receive the noise or acquires the noise through electrical wiring.
