DENOISING METHOD FOR SINGLE EPOCH GPS DEFORMATION MONITORING SIGNAL BASED ON LIFTING WAVELET
摘要
Abstract
The threshold shrinkage denoising method based on lifting wavelet transform is expatiated. Besides,the method is used to filter the noise from single epoch GPS deformation monitoring data and get the real deformation information. The experimental data processing results show that the advantage of lifting wavelet transform lies on better denoising effect and consuming shorter time than traditional wavelet transform.关键词
