On the use of short-time fourier transform and synchrosqueezing-based demodulation for the retrieval of the modes of multicomponent signals

In this paper, our goal is to compare different recent time-frequency (TF) approaches retrieve the modes of multicomponent signals (MCSs). While it acknowledged that synchrosqueezing transform (SST) improves readability representation (TFR) MCSs, and SST-based demodulation (DSST) more efficient than SST itself for mode retrieval (MR), unclear whether DSST outperforms downsampled short-time Fourier (STFT) in matter. The present paper answer question propose a variant reduces mode-mixing. focus put on sensitivity techniques frequency modulation resolution.
