An Improved Wavelet Threshold Denoising Algorithm for Analysing Signals in the XRD Spectrum
丽 牟 · Advances in Applied Mathematics · 2015
In this paper, a new threshold function is put forward, which is based on the introduced wavelet threshold function.The new threshold function not only has the advantage of traditional ones but also is continuous.Experiments show that the denoising algorithm based on the new wavelet threshold function can remove the noise in the XRD spectrum more effectively and is more beneficial for qualitative and quantitative analysis.
