GNSS Signal Acquisition in the Presence of Bit Transition

摘要：

　　In the acquisition block of a real time recelver for satellite communlcation,bit transition due to the navigation message may cause a correlation peak splitting,which will probably lead to a wrong estimation of Doppler shift and code Phase delay.In this paper,the impact of bit transition on the acquisition is analyzed and a scheme named modified time parallel acquisition(MTPA)with the discrete Fourier transform(DFT)operation applied to,is proposed to solve the problem.The simulation results and performance curves show that the MTPA scheme is promising.
