Generalized Cepstrum Correlation Function Analysis Method on Multipath Signals of GPS
Dong Xu-rong · 2008
Based on the principle of cepstrum analysis method,two principle and processing diagrams of the cepstrum analysis and the generalized cepstrum correlation analysis are given for the GPS multipath signals analysis.The main processes are simulated with Matlab.The simulation results demonstrate: the generalized cepstrum correlation function method is superior to the cepstrum method in the estimation of delay time.It can also cancel the affects of the transmitter source,path transmission function and convolution interference.In the apartment of direct and multipath signal,the cepstrum method is utilized more often.
