Abstract:
A control device of a receiving device includes an interference wave detector that detects an interference wave within an intermediate frequency band in a signal converted by a mixer that converts a reception signal of a radio frequency band with a certain radio frequency as a center into an intermediate signal of the intermediate frequency band based on a signal of a local oscillation frequency different from the radio frequency. The control device further includes a frequency controller that changes the local oscillation frequency so that the intermediate frequency band gets away from a band of the interference wave when the interference wave is detected.
