Abstract

The noise is one of the main factors affecting the receiver sensitivity. And the periodically non-uniform sampling model is an effective way to break through the limitation of the Shannon’s sampling theorem. In this paper, we make an analysis about the linearity of the periodically non-uniform sampling system and its noise characteristics. Besides, we acquire the time-varying Gaussian probability density function of the output noise. And then the output noise after sampling is proved to be the colored noise, which is cycle-stationary and can be whitened through the method proposed in the paper. Finally, the simulation results are given to verify the correctness of the analysis.
