Research on Hilbert-Huang transform

Nonlinear and non-stationary signal processing has been always a hot issue.Hilbert-Huang transform is a new signal processing method,which can get the time-frequency-energy distribution characteristics of the signals through the empirical mode decomposition(EMD) and Hilbert transform.But when it is in application,the results gained are not very precise,some improvements are proposed,and it proved feasibility and useful through MATLAB simulation.
