GPS中频信号模拟研究

Research on IF GPS Signal Simulator

研究了GPS中频信号数据的模拟。在分析GPS中频数字信号模型的基础上,研究了中频信号模拟的结构及实现,包括GPS信号传播环境模拟、GPS发射信号模拟、滤波和量化过程,最后给出模拟器的软件实现。本文的研究对GPS的工程应用和软件接收机的研究具有一定的理论和工程意义。

IF GPS signal simulation is implemented in this paper. The structure and realization of IF GPS signal simulator are also studied, including simulation of GPS signal propagation environment,GPS signal,signal filtering and quantization, with the software flow chart presented in the last. The research work in this paper should be valuable in the project application and the theory research of GPS software receiver.
