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

- 用于希尔伯特变换，里面有HHT谱计算程序，不是rilling版本，用改进的Hilbert变换，效果好一些，供大家参考-HHT spectrum of the calculation procedures, rilling is not a version of the Hilbert transform used to improve the results better for your reference.

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
