- 对信号进行DWT分解,并对信号进行水印提取重构,测试信噪比-decompose signal by DWT,watermark the watermarking test it s PSNR
diagnosis--based-on-LEM
- A novel fault feature extraction method based on the local mean decomposition technology and multi-scale entropy is proposed in this paper. When fault occurs in roller bearings, the vibration signals picked up would exactly display non-stationary

- EEMD skillfully solves the mode mixing problem by adding a white noise to the original signal. (3) The synthetic signal example reveals the remarkable ability of EEMD to decompose the signal into different IMFs and analyze the time–frequency distribu

- 最近的一些方法,如经验模式分解 (EMD),提出将信号分解 其包含的信息。尽管它的适应性似乎 对于许多应用程序,这种方法的主要问题 是它缺乏理论。本文提出了一种新的方法 建立自适应小波。主要的想法是提取不同 设计适当的小波滤波器组的信号模式。 这种结构导致我们到一个新的小波变换,称为 经验小波变换。许多实验 显示此方法相比经典的有用性 EMD-Some recent methods, like the Empirical Mode Decompositio
