Query: Reconstruction of Supernova Gravitational Waves Waveforms: Comparing
  Three Time-frequency Transform Methods   For supernovae gravitational wave signal analysis which intend to reconstruct
supernova gravitational waves waveforms, we compare the performance of
short-time Fourier transform (STFT), the synchroextracting transform (SET) and
multisynchrosqueezing transform (MSST) by a self-consistent time-frequency
analysis based pipeline. The simulated supernovae waveforms injected into white
noise are identified by a hierarchical clustering method in the time-frequency
map and then reconstructed by the inverse time-frequency transforms. We find
that in terms of signal reconstruction, the SET method performed the best,
especially much better than traditional STFT method in reconstructing signals
from data with white noise when valued the signal-to-noise ratio. While
concerning the quality of time-frequency figures, the MSST method and SET
method have less energy dispersion and were both better than STFT method. The
higher energy dispersion in time-frequency figure of STFT is time consuming in
the clustering process and reduce the accuracy of signal identification. Our
preliminary conclusion is that the SET method is the suitable method for the
supernovae gravitational wave signal analysis pipeline though more tests are
stilled needed.
