Abstract: An operation method of a receiving device may comprise: receiving a periodic band-limited signal from a transmitting device; determining whether a carrier frequency of the periodic band-limited signal satisfies a constraint; converting the periodic band-limited signal into a digital high-frequency band signal by sampling the periodic band-limited signal at an extraction rate equal to or less than a Nyquist extraction rate when the carrier frequency satisfies the constraint; down-converting the digital high-frequency band signal into a digital baseband signal; rearranging samples of a plurality of periods of the digital baseband signal into one period; and generating a reconstructed signal by performing low-pass filtering with a bandwidth of the periodic band-limited signal on the digital baseband signal in which the samples are rearranged.
