| Abstract: | In this paper, several wavelet denoising methods are compared and analyzed. On these bases, a new threshold function is constructed. The improvement of threshold selecting is made. Simulation experiment of signal denoising is carried out using MATLAB software. The advantage of improved wavelet denoising method is demonstrated, and better denoising effect is gained. |
