An efficient method is presented to find the minimum valid sampling frequency for bandpasssampling of multiband signals in software defined radio (SDR) technology.
In this paper, we first obtain the FRFT of the uniform impulse-train sampled signals, and based on it, we deduce sampling theorem and reconstruction formula for bandpass and lowpass signals with FRFT.
