| 摘 要： | 研究了基于通用软件无线电外设(USRP)的北斗信号仿真系统。给出了北斗卫星电文的生成方式,使用Matlab读取星历信息并定义编码产生北斗卫星信号,并利用USRP实现北斗卫星电文的调制发射,利用接收机对该信号进行捕获接收,并对信号附加的多普勒频移进行仿真。最后通过接收机对仿真系统产生的信号进行接收验证。通过此仿真系统可更直观地研究北斗卫星信号,对研究北斗卫星导航系统具有一定的参考意义。

| Abstract: | Beidou signal simulation system based on universal software radio peripheral (USRP) is studied in this paper.Beidou satellite message generating method is given, Matlab is used to read ephemeris and define code to generate Beidou satellite signal, and USRP is used to realize the modulated emission of Beidou satellite message, then this signal is captured and received by the receiver, and Doppler frequency shift of signal added is simulated, finally, the receiver received the signal from the simulation system and verified it.Through this simulation system, Beidou satellite signal can be more intuitively and conveniently studied, which has certain reference significance for the research of Beidou satellite navigation system. |
