Time-frequency analysis of seismic data using synchrosqueezing wavelet transform |

where is the chosen mother wavelet, denotes the complex conjugate of . The instantaneous frequency of for signal can be got by:

The synchrosqueezed transform can be determined only at the centers of the successive bins , with , by summing different contributions (Daubechies et al., 2011):

The SSWT is invertible and the original signal can be obtained by:
