EEMD相关文件
- 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,最终用瞬时频率和能量来

emd
- 该方法的关键是经验模式分解,它能使复杂信号分解为有限个本征模函数(Intrinsic Mode Function,简称IMF),所分解出来的各IMF分量包含了原信号的不同时间尺度的局部特征信号。经验模态分解法能使非平稳数据进行平稳化处理,然后进行希尔伯特变换获得时频谱图,得到有物理意义的频率。与短时傅立叶变换、小波分解等方法相比,这种方法是直观的、直接的、后验的和自适应的,因为基函数是由数据本身所分解得到。由于分解是基于信号序列时间尺度的局部特性,因此具有自适应性。(The key of thi
