Software-defined radio (SDR) can support multiple communication standards and provide flexible services. In this paper, a feasible radio frequency (RF) bandpass sampling architecture of single-channel SDR receiver is proposed. The tradeoff between the sampling frequency and resolution of the analog-to-digital converter (ADC) and the selectivity and tunability of the bandpass filter provides a natural...
In this letter, we consider a case in which only one radio frequency (RF) signal is of interest over multiple RF signals with contiguous spectrums (i.e., these RF signals are adjacent to each other). The minimum valid bandpass sampling range for a desired RF signal over multiple ones is derived under the assumption of contiguous spectrums. The sampling frequency confined by the derived minimum valid...
