ABSTRACT
The universal method to analysis non-stationary signal in reality, and the analysis methods are based on time-frequency domain or time-scale domain. An invertible transform method based on time series is proposed in this paper from another point of view. Using this method to analyze the broadband noise signal, experiments show that this method can turn disorder to order in time domain. And after transform, their characters distinguish noise signal, speech signal from each other. The principle is simple, easy to achieve.
