Yunyu Zhang · Telecommunication Engineering · 2007
Based on the theoretic modeling and analysis of the IF GPS signals,an accurate software simulator of IF GPS signals is implemented in Matlab/Simulink,the effects of noise,under-sampling and receiver clock error are also simulated.Convenient for the realization of different algorithms,the software simulator is implemented by combining Matlab code with Simulink models.Compared to conventional GPS signal simulators,this software simulator has many advantages,such as nimble design,flexible extending and easy-touse.
