Title: Instantaneous Frequency Estimation Based on Adaptive Time-Frequency Distribution
Abstract: An instantaneous frequency estimation based on adaptive optimal kernel time-frequency distribution and a modified algorithm are proposed in order to enhance the instantaneous frequency estimation of multicomponent signal in noise environment.In the computation of modified algorithm,a new adaptive time-frequency distribution based on Gabor transform and Wigner-Ville distribution is obtained.Simulation and real data analysis show that the modified algorithm has the properties of low variance and calculational complexity.
