An Improved Method of Multi-path Signal Suppression for GPS

Through the analysis Teager-Kaiser algorithm and multipath delay lock loop technique(estimated MEDLL), a kind of new algorithm for GPS multipath inhibition is put forward.The new algorithm in combination with TK algorithm based on improved MEDLL technology can attain the multipath signal parameters.It is able to separate the multi-path signal from received signal, and also reduces the impacts from multi-path signals.At last, the simulation is conducted by computer.The results obtained show that the time error of the improved estimation is less than that of MEDLL estimation.
