Abstract

In signal processing, the estimation of instantaneous frequency is a kind of very important issue for non-stationary multi-component signal. Firstly, this paper adopts EMD decomposition to decompose non-stationary multi-component signal and convert into a series of single component signal. Then using the method of hilber transform and teager energy operator respectively, the instantaneous frequency of single component can be obtained. Finally, the simulation results show that adopting hilber transform can make root-mean-square error of instantaneous frequency and amplitude of fluctuation more smaller. So this method presented in the paper is feasible and effective.
