基于希尔伯特-黄变换的信号处理方法

摘要

It is not good in Common signal processing method for non-stationary signal processing effect .In 1998 ,N .E .Huang et al developed a new method called Hilbert Huang Transform (HHT ) . This method should be established in empirical mode decomposition (EMD ) based on the decomposition of the signal is obtained , by an intrinsic mode function (IM F ) . According to the intrinsic mode function for HHT .This article mainly introduces the basic principle of the method of Hilbert Huang transform ,and applied in the detection of aluminum electrolysis anode effect .%常用的信号处理方法对于非平稳信号处理效果不佳.1998年 ,N .E . H uang等研究出了一种新方法 希尔伯特黄变换(HHT ).这种方法要建立在经验模式分解(EMD)的基础上 ,通过分解获得信号的一种本征模函数(IMF) ,再根据本征模函数进行 HHT.文中主要介绍了希尔伯特-黄变换方法的基本原理 ,并应用在铝电解阳极效应检测中.
