Hilbert-Huang希尔伯特黄变换(HHT)的Matlab实现
- 代码中的plot_hht函数实现了Hilbert-Huang变换(HHT),HHT就是Hilbert-Huang Transform(希尔伯特黄变换),美国航天航空局黄鳄教授发明的,大概的过程是:先对信号进行经验模态分解(Empirical mode decomposition -EMD),得出本征模态函数(IMF intrinsic mode function),再对本征模态函数进行希尔伯特变换,从而过进一步得该信号的希尔伯特谱、时频能量谱等,以便对信号进行分析,据介绍对非线性及非平稳信号有较

希尔伯特黄变换
- HHT主要内容包含两部分,第一部分为经验模态分解(Empirical Mode Decomposition,简称EMD),它是由Huang提出的;第二部分为Hilbert谱分析(Hilbert Spectrum Analysis,简称HSA)。简单说来,HHT处理非平稳信号的基本过程是:首先利用EMD方法将给定的信号分解为若干固有模态函数(以Intrinsic Mode Function或IMF表示,也称作本征模态函数),这些IMF是满足一定条件的分量;然后,对每一个IMF进行Hilbert变换
