Abstract

In this paper, a simulation design of digital IF signal based on the mathematical model of digital IF GPS signals is proposed. This design based on the traditional simulation of C/A code includes C / A code generator, navigation data generator and the P code generator, and the noise which can set the SNR simultaneously. Experimental results show that the structure of simulated signals is closer to real signals compared with traditional design and the simulated signals have the same properties with real signals. It can also provide signal source for various signal processing algorithms of GPS receivers.
