ConceFT: Concentration of frequency and time via a multitapered synchrosqueezed transform

Ingrid Daubechies, Yi Wang, Hau Tieng Wu

Abstract: A new method is proposed to determine the time-frequency content of time-dependent signals consisting of multiple oscillatory components, with time-varying amplitudes and instantaneous frequencies. Numerical experiments as well as a theoretical analysis are presented to assess its effectiveness.
