N2 - Bandpass sampling is a useful digital method for direct downconversion without analog mixer. Therefore, this sampling method is essential for the software-defined radio (SDR) system to be required minimization of RF front-end. Also, the bandpass sampling system can be extended to accommodation of multiple standards for the future wireless communication systems. This paper proposes a novel downconversion scheme for multiple standards based on a complex bandpass sampling method. It includes generalized formulae derivation for the available sampling range, the signal's intermediate frequency (IF) and the minimum sampling frequency for the multiple RF signals. And we verify from simulation results that the proposed system is more flexible and suitable than a real bandpass sampling system.
