Wavelet de-noising of GPS single epoch deformation signals

WANG Jian, SUN Xiang-zhong, GAO Jing-xiang (College of Environment and Spatial-Infonnatics, of CUMT,Xuzhou 221008)  
Wavelet transform, multi-resolution analysis theory and rnediam valuefilter technique are discussed in this peper. Compared with forced wavelet de-noising method and Soft-thresholding noise reduction, a new Wavelet De-noising method based on median value filter of high frequency of single epoch GPS deformation monitoring signals is proposed.Experimental results show that the proposed method can get perfect de-noising effects, keeping smooth properties of the signal as well as eliminating some gross errors.
