A new envelope algorithm of Hilbert-Huang Transform

TL;DR: A new envelope algorithm, the segment power function method, is put forward that is superior to existing algorithms because in most situations it is more flexible than the cubic spline interpolation algorithm and smoother than the Akima interpolation algorithms, and it is less likely to introduce a false frequency when applied to HHT.
Journal ArticleDOI

Research on iterated Hilbert transform and its application in mechanical fault diagnosis

TL;DR: In this article, a new method for mechanical fault diagnosis based on iterated Hilbert transform (IHT) is proposed, and the analysis results of the mechanical fault signals show that the weak features of these signals can be efficiently extracted with the proposed approach.
Journal ArticleDOI

Research on the unified mathematical model for FT, STFT and WT and its applications

TL;DR: In this article, a unified mathematical model for some classical signal transforms is presented and discussed, and the specific values of the variables and parameter functions of FT, STFT and WT are given.

Accurate instantaneous frequency estimation with iterated Hilbert transform and its application

TL;DR: In this article, a smoothed instantaneous frequency estimation (SIFE) method based on difference operator and zero-phase digital low-pass filtering is proposed for fault diagnosis of a rolling bearing, and the simulation results show that the proposed approach has higher performance than the adaptive segmentation algorithm and Hilbert-Huang transform.
