Abstract：Hilbert-Huang Transform (HHT) is a new method for processing non-linear and non-stationary signals, which could be dated back to the end of the 20th century. Meanwhile, boundary process is one of its key technologies. This paper focus on introducing a method for EMD boundary process based on Intrinsic Wave Matching —— Intrinsic Wave Matching Prediction Method, especially on introducing the comparison between two representative EMD boundary process methods and Intrinsic Wave Matching Prediction Method in processing simulated signals and tested signals., which validates the advance of Intrinsic Wave Matching Prediction Method. Works of this paper deepen and perfect the existing correlative researches to great degree.
