Optimization of the End Effect of Hilbert-Huang transform (HAT)

In fault diagnosis of rotating machinery, Hil- bert-Huang transform (HHT) is often used to extract the fault characteristic signal and analyze decomposition results in time-frequency domain. However, end effect occurs in HHT, which leads to a series of problems such as modal aliasing and false IMF (...
