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.

摘要

提出了一种新方法来确定由多个振荡分量组成的、具有时变幅度和瞬时频率的时变信号的时频内容。给出了数值实验以及理论分析来评估其有效性。
