【Abstract】 For the research of frequency domain correlation acquisition algorithm and its implementation in embedded GPS software receiver,a model of two-step acquisition algorithm is adopted and simulated in Matlab. The simulation results show that the algorithm is correct and superior. Finally,the algorithm is implemented in C and executed on the GT3000A platform,SoC with an ARCA 3 CPU core,succeeding in the acquisition of real GPS signal and providing a reference for the study of embedded software receiver.更多还原
