摘要: We propose to combine cepstrum and nonlinear time-frequency (TF) analysis study mutiple component oscillatory signals with time-varying frequency amplitude non-sinusoidal pattern. The concept of is applied eliminate the wave-shape function influence on TF analysis, we a new algorithm, named de-shape synchrosqueezing transform (de-shape SST). mathematical model, adaptive non-harmonic introduced SST algorithm theoretically analyzed. In addition simulated signals, several different physiological, musical biological are analyzed illustrate proposed algorithm.
