HHT
- 基于经验模态分解法(EMD)的Hilbert-Huang变换(HHT)的MATLAB程序。 可将非平稳信号转换为平稳信号,通过将IMF分量累加重构得到平稳信号 。 主程序为HHT.m,需要用到hhspectrum.m函数、instfreq.m函数(在压缩包内)和已安装的EMD工具箱中emd函数。(The empirical mode decomposition (EMD) method based on Hilbert-Huang transform (HHT) of the MATLAB
decomposition
- 运行emd,得到输入信号X的固有模态函数(imf),每列代表着信号X的一阶分量,X就是我们采集的信号。 hhtdn是hht去噪的程序,可以不看,仅看emd 和 findpeaks wvtdn是wavelet去噪程序,如果只是分解信号,仅用下面的语句即可 [C,L] = wavedec(x_noise,dl,wn); x_noise就是我们采集的信号,dl是分解的阶数,wn是分解的母小波名称(% Empiricial Mode Decomposition (Hilbert-Huang

EMD模型
- 经验模态分解(Empirical Mode Decomposition,简称EMD))方法被认为是2000年来以傅立叶变换为基础的线性和稳态频谱分析的一个重大突破?,该方法是依据数据自身的时间尺度特征来进行信号分解,无须预先设定任何基函数。 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
