摘要
希尔伯特-黄变换包括两个主要步骤:经验模态分解和希尔伯特变换;在经验模态分解过程中会产生的端点效应,应采取方法抑制;能应用于多个领域。
Hilbert-Huang Transform,which was developed by Norden E Huang of NASA in 1998,is a new meth- od of Time-Frequency analysis.The major parts of this method,empirical mode decomposition and Hilbert trans- form,were introduced in detail in this paper.Its end effects,which are produced in the decomposition of empirical mode decomposition processed,and restrained methods are also analyzed.At last,some applied fields and exam- ples of this method are discussed briefly.
