Subsampling optimization for signal in the presence of interferer in nonlinear systems

摘要

This paper presents a design approach to determine the subsampling frequency ranges for a multi band system, where only one signal is prioritized so that it doesn't overlap with the other signals during the subsampling process. The proposed technique will introduce the formulas derived from an existing method to relax the conditions on the other signals in the multi band case. The results show that by having this assumption, the subsampling frequency needed to extract the desired signal is lower than the previously derived methods.
