BPSK/BOC Modulation Signal System for GPS Satellite Navigation Signals

Abstract With the continuous research and development of global positioning system in various countries, requirements for accuracy efficiency GPS signals are getting higher higher. To improve performance signal modulation, this focuses on BPSK modulation BOC introduces basic principles practical uses two signals. Based disadvantage weak anti-noise modulated high ambiguity signal, algorithms signal-to-noise ratio estimation parallel phase code acquisition introduced paper. By introducing functions algorithms, improvement optimization algorithm is expounded. This paper working principle shows advantages future prospects based compares with algorithm. The superior performance. Combined algorithm, high-precision transmission can be achieved, but receiver high. combined meet most needs life. Still, it slightly worse than face high-demand transmission.
