| Abstract: | The basic theory of wavelet transition was introduced. And the practical ultraviolate signal was processed with db8 wavelet to eliminate noise. The method of hard threshold was compared with the method of soft threshold through numerical simulations. The result showed that the method of soft threshold is better. And the noise in the signal was effectively eliminated by it and the Signal-to-Noise was enhanced to 8. 5192dB. |
