Instantaneous Frequency Identification Using Adaptive Linear Chirplet Transform and Matching Pursuit

An instantaneous frequency identification method of vibration signal based on linear chirplet transform and Wigner-Ville distribution is presented. This method has an obvious advantage in identifying closely spaced and time-varying frequencies. The matching pursuit algorithm is employed to select op...
