Abstract :
In this paper, authors point out the effect of non uniform sampling (NUS) on the power consumption in SDR receiver baseband stage. This feature is drawn by theoretical formulas regarding spectrum shape and power estimation of different baseband components. An example is drawn to focus on NUS ability to reduce anti-aliasing filter (AAF) consumption by 25%.
