TITLENonstationary Time Series Analysis with Modern Signal Processing Techniques IX

ABSTRACT List of topics :
1. Linear type time-frequency analysis tools, particularly short-time Fourier transform (STFT) and continuous wavelet transform (CWT)
2. Nonlinear type time-frequency analysis tools, particularly reassignment technique like synchrosqueezing transform (SST) and its variations and a comparison with (ensemble) empirical mode decomposition (EMD)
3. Wave-shape analysis and de-shape algorithm
4. Ridge detection and multi-component decomposition algorithm like shape-adaptive mode decomposition (SAMD)
5. Time-varying bandpass filter and phase analysis
6. Noise suppression by multi-taper analysis and concentration of Frequency and Time (ConceFT)
