EMD-ICA with Reference Signal Method and Its Application in GPS Multipath

LUO Feixue 1,2,DAI Wujiao 1,2,TANG Chengpan1,2,HUANG Dawei1,2,WU Xixiu1,2 1.Department of Surveying Engineering & Geo-Informatics,Central South University,Changsha 410083,China;2.Key Laboratory of Precise Engineering Surveying and Deformation Disaster Monitoring of Hunan Province,Changsha 410083,China  
Multipath error is a main influence on high-precision GPS dynamic deformation monitoring results as it is difficult to be mitigated by difference observation in most of applications.A method called EMD-ICA with reference signal is proposed.It combines empirical mode decomposition(EMD) with independent component analysis(ICA).The test shows the effectiveness of this method.
