GPS Pseudo-random Code Simulation in Time Domain and Frequency Domain

At present, the GPS system is used more and more widely, and the research on the GPS signal is the basis in this field. Therefore, based on the basic principle and structure of the satellite signal, and aim at the pseudo-random code C/A-code, P-code's characteristics character which GPS signal adopt analysis and research the production method, then simulation the realization based on Matlab/Simulink simulation-platform. Focus on demonstration the production process of C/A-code, P-code, the simulation results in line with the character of the reality signal.
