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

优秀论文及配套源码。Hilbert-Huang变换(HHT)是一种新的非平稳信号处理技术,该方法由经验模态 分解(EMD)与Hilbert谱分析两部分组成。任意的非平稳信号首先经过EMD方法处理后被分解为一系列具有不同特征尺度的数据序列,每一个序列称为一个固有模态函数(IMF),然后对每个IMF分量进行Hilbert谱分析得到相应分量的Hilbert谱,汇总所有Hilbert谱就得到了原信号的谱图。该方法从本质上讲是对非平稳信号进行平稳化处理,将信号中真实存在的不同尺度波动或趋势逐级分解出来,最
