基于小波变换的正交匹配追踪算法及其应用先介绍了压缩感知的基本原理以及理论模型,然后详细阐述了匹配追踪(Ⅷ)以及正交匹配追踪(()脚)
两种重构算法,进而提出了基于小波变换的正交匹配追踪算法(wOⅧ),即先将信号经过单层小波变换,保留信号的
低频部分,只对高频稀疏部分进行压缩,然后利用正交匹配追踪算法进行重构,最后对低频及处理后得到的高频部分
进行小波反变换得到重构信号。(Based on orthogonal wavelet transform matching tracking algorithm and its application to the basic principles and theoretical models compressed sensing, and then elaborated matching pursuit (Ⅷ) and orthogonal matching pursuit )

HHT
目前,互联网上HHT信号处理技术有
三种实现方式,采用MATLAB编程语言,一种是法国研究者设计的G Rilling 2007
另一种是MATLAB文件交换中心由Alan Tan开发的plot_hht程序包,第三种是台湾中央大学数据研究中心提供的EEMD包。
其中,我使用了plot_hht程序包,其使用了三个终止条件,驻留分量的单调性,极值点与零点的个数相差不超过1,还有黄锷1998经典文献提出的
SD>0.1,单调性的判断,并不是去判定驻留分量是否是单调函数,而是当曲线是双曲线时,循环结束,由于没有考虑端点效应,程序比较简洁,好读懂,大家
学习HHT可以从这个程序包入手,在此抛砖引玉,希冀有人能比较这三种不同的算法的性能和时间复杂度,以及对各种信号的适应性。
(There provides three types of HTT program packages: one developed by France researcher G. Rilling 2007, the other provided by by Alan Tan from Matlab file exchange center and the third one by Taiwan Central University Data Research Center. Please start from the simple one by Tan to learn more.)
