Abstract：Threshold denoising in wavelet domain is an efficient method to reduce the white noise which is easy to program, so that it is widely applied to the image and signal denoising. According to the wavelet transformation characteristic of the MMV target radiation signal, the non-negative wavelet coefficient is used to replace the wavelet coefficient of the signal. For the definite threshold, denoising method of the non-negative wavelet coefficient is inferred when the MSE of the reconfigurable signal is minimized. Experiments show that the method can suppress the noise effectively.
