Wavelet analysis plays an important role in signal processing because of its good time-frequency locality and multi-resolution analysis performance.Based on wavelet analysis in one-dimensional signal denoising are studied, and the principle of threshold and threshold function of wavelet threshold denoising, the selection of wavelet base, decomposition layers and other related issues, and the relevant numerical experiments with Matlab software.
