Abstract
There is provided a calibration device including: a calibration signal supply unit configured to supply, as a calibration input signal, a multitone signal having tones in a plurality of frequency bands to a converter configured to multiply an input signal by each of a plurality of signal patterns and limit a band to obtain each of a plurality of bandpass signals, and reconstruct an output signal in accordance with an input signal from the plurality of bandpass signals; a calibration bandpass signal acquisition unit configured to acquire a plurality of calibration bandpass signals obtained by the converter in response to the multitone signal; and a calibration processing unit configured to calibrate a parameter for the reconstruction in the converter based on the plurality of calibration bandpass signals.
