Noise Smoothing for Structural Vibration Test Signals Using an Improved Wavelet Thresholding Technique

Noise Smoothing for Structural Vibration Test Signals Using an Improved Wavelet Thresholding Technique

In structural vibration tests, one of the main factors which disturb the reliability and accuracy of the results are the noise signals encountered. To overcome this deficiency, this paper presents a discrete wavelet transform (DWT) approach to denoise the measured signals. The denoising performance...
