In this paper, we decide to study a some of non uniform sampling (NUS) schemes, particularly its random processes schemes; jittered random sampling (JS) and the additive random sampling (ARS) and and its application for a RF bandpass sampling receiver. These techniques sampling has desirable alias suppression properties. First, effects of jittered and additive random sampling to suppress aliasing artifacts are detailed. Then, we propose a robust RF bandpass sampling receiver using NUS schemes. Finally, performance of JS and ARS schemes on reconstruction SNR for bandpass signals are compared. Simulation results give that JS with uniform distribution is the robusted technique on the terms of SNR.
