Abstract :
A time-frequency analysis method based on the modeling of time-varying parameters is discussed in detail in this paper. The major traits of this method are that the calculating consumption is small enough by adopting recursive algorithm to analyze non-stationary signals, and the resolutions of both time and frequency are good without cross-item interference. In the end, the method is proved to be valid by simulation
