  Abstract

A bandpass sampling technique, which is a method directly downconverting a bandpass signal to a baseband or a low IF signal without analog mixers, can be an alternative choice for the SDR system to minimize the RF front-end. In this paper, a complex bandpass sampling technique for two bandpass-filtered signals is proposed. We derived generalized formulae for the available sampling range, the signal’s IF and the minimum sampling frequency taking into consideration the guard-bands for the multiple RF signals. Thru the simulation experiments, the advantages of the complex bandpass sampling over the pre-reported real bandpass sampling are investigated for applications in the SDR design.
