On Local Chirp Rate Estimation in Noisy Multicomponent Signals: With an Application to Mode Reconstruction

In this paper, our goal is to investigate local chirp rate (CR) estimation in noisy multicomponent signals. The focus is put on improving a specific type of local CR estimator used in the second order synchrosqueezing transform, which proves to be very inaccurate in the presence of noise. More preci...
