| Abstract: | The basic theory of wavelet transform is introduced. The methods and steps of signal processing based on wavelet transform are presented. Daubechies8 wavelet is selected to de-noising the measured ultraviolet signal. The experimental results show that wavelet threshold de-noising is very effective for de-noising the ultraviolet signals. Signal to noise ratio improvement is 8. 519 2 dB. |
| Keywords: | wavelet transform ultraviolet light signal wavelet threshold de-noising signal to noise ratio |
