摘要：

In this paper, emphasis is placed on de-noising via thresholding, which is based on wavelet transform. This paper also analyses the characteristic of signal and noise by wavelet transform, de-noising method by Donoho and other's improving scheme. According to the feature of noise and the continuity of signal, the improvement schemes are put forward on dealing with the preprocessing procedure to signal observation. These schemes are uncomplicated and practical.
