Daubechies et al. proposed a novel approach combining wavelet transform with reassignment—the synchrosqueezed wavelet transform. This method effectively reorganizes the time-frequency representation obtained from wavelet transform to achieve higher frequency resolution in time-frequency curves. Additionally, it enables decomposition of arbitrary signals into linear combinations of approximately harmonic components. The implementation typically involves MATLAB's cwt function for continuous wavelet transform, followed by frequency reassignment through phase differentiation and spectral squeezing operations.
