Software Defined Radio, Multiple RF signals, Bandpass Sampling Range, and Sampling Range Formulas.


The receiver on the basis of Software Defined Radio has a single hardware supporting various communication stan dards by using software. In this receiver, to recover each baseband signal, the received Radio Frequency(RF) signals should be directly down-converted to an Intermediate Fre quency in digital domain by an Analog to Digital Converter using the bandpass sampling scheme. In this paper, we propose a bandpass sampling scheme to get the digital signal with multiple IF spectrums arranged in order of carrier frequency. In addition, a gen eralized formula is derived to choose the valid bandpass sampling range for the multiple distinct RF signals. The formula is verified by using SystemV iewT M simulation.
