基于EMD-ARmodel和支持向量基的非线性振动信号的文章，学习非线性的同学可以看下，外文的来自I-Feature Extraction & Application of Engineering Non-stationary Signals Based on EMD-AR Model and SVD

调用程序可对信号进行EMD分解，再进行奇异值分解降噪(The calling program can decompose the signal by EMD, then the singular value decomposition and denoising 2D empirical wavelet program. The calling subroutine can perform the empirical wavelet transform on the image.)

通过峭度指标与互相关系数筛选IMF进行SVD分解去噪(Filtering IMF for SVD denoising by kurtosis index and correlation number)
