HIGHLIGHTS
- who: Chengjie Wei and collaborators from the Zhengzhou, Henan, China Mohammed, Central University of Punjab, Bathinda, India have published the article: Railway foreign body vibration signal detection based on wavelet analysis, in the Journal: (JOURNAL)
- what: For the initial signal with noise, first, the initial signal is denoised based on the wavelet packet denoising method of compromise threshold, remove the influence of noise, then, based on the wavelet energy spectrum method, the proportion of the de-noised signal in each frequency band is calculated, it can effectively extract the distribution characteristics of the measured signal . . .
