Discussion about quality evaluation on wavelet transformation of GPS continuous observation data
Guohua Yang · Cehui kexue · 2011
Wavelet transform has good effects in the application of processing GPS noise.The paper studied on the evaluation quality of wavelet transform de-noising of GPS continuous data,by using different radical functions for wavelet transform of analysis data and analyzing each scale result by wavelet transform under the same radical function,and finally obtained a primary conclusion that it would be appropriate and reasonable to use sym6,sym8,and coif4 wavelet and 4~6 decomposition level for the wavelet transform de-noising of GPS continuous data..
