Abstract :
This paper proposes a novel spectrally-efficient down-conversion scheme based on complex bandpass sampling (CBPS) for downconversion of multiple radio frequency (RF) signals. It was investigated the valid sampling range and the minimum sampling frequency of the complex bandpass sampling. Its effectiveness was verified by comparing with real bandpass sampling scheme, and its implementation issues were also discussed
