论文摘要
这项研究提出了使用新的瞬时频率局部估计值对短期基于傅立叶的同步转换的概括。这种技术不仅可以实现高度集中的时频表示，以实现各种AM-FM多组分信号，而且还可以以高精度重建其模式。对合成和重力波信号的数值研究显示了这种新方法的效率。
This study puts forward a generalization of the short-time Fourier-based Synchrosqueezing Transform using a new local estimate of instantaneous frequency. Such a technique enables not only to achieve a highly concentrated time-frequency representation for a wide variety of AM-FM multicomponent signals but also to reconstruct their modes with a high accuracy. Numerical investigation on synthetic and gravitational-wave signals shows the efficiency of this new approach.
