The Research of Compression Awareness Based on Non-uniform Observations

Abstract

Non-uniform sampling randomly selects several "scattered" samples to represent the original signal in the time domain signal. Unlike CS in which each observation is the original signal of a holographic perception, it is called "scattered". However, more in-depth studies have found that they are essentially identical because a very narrow pulse sampling signal in the time domain corresponds to a wide frequency domain signal in the frequency domain, and this wideband signal can be used as a signal to perceive the original signal A. In this way non-uniform sampling and CS can be unified together, and only the perception of the domain only.
