Non-uniform sampling schemes for IF sampling radio receiver

The IF sampling radio receiver based on the non-uniform sampling (NUS), technique is promising and would be a candidate for the multistandard reception. This technique allows the IF down-conversion and permit to eliminate or alleviate the anti-aliasing filter. For wideband and multistandards design, the choice of sampling rates for bandpass sampling is flexible. This paper introduces the NUS theory, particularly its random processes schemes; the additive random sampling (ARS) and the jittered random sampling (JRS). Then, it proposes the IF NUS receiver architecture. The reconstruction algorithm RA block represents the object of the comparison between the sampling schemes. Finally, validation of the algorithm, its anti-aliasing specificity and some simulation results are presented
