This article provides a general overview of time-frequency (T-F) reassignment and synchrosqueezing techniques applied to multicomponent signals, covering the theoretical background and applications. We explain how synchrosqueezing can be viewed as a special case of reassignment enabling mode reconstruction and place emphasis on the interest of using such T-F distributions throughout with illustrative examples.

Theoretical analysis of the second-order synchrosqueezing transform (2016, methodology): “To better take into account the frequency modulation, in the FSST context, a first approach based on the definition of a demodulation operator was proposed in [13], while a new synchrosqueezing operator based on a new chirp rate estimate was defined in [16, 2].”
Multisynchrosqueezing Transform (2019, methodology): “If we substitute Ts[2](t, η) into Ts[3](t, η), the MSST (N = 3) can be derived as follows:”
