| Abstract: | In this paper,the fundamental and operating process of wavelet de-noising are briefly presented.Then some wavelet functions and threshold determine methods are adopted to compare the effect of de-noising in processing of GPS dynamic monitoring data.The results demonstrate that by wavelet analysis,the effect of de-noising can be realized. |
