摘要
本文介绍了伽利略卫星导航系统E5段的信号结构,新型调制方式BOC的基本原理和在E5中的应用,并对伽利略E5信号的结构作了分析和简化,验证了E5段的Alt BOC信号在接收端可以近似为一个QPSK信号,最后给出了对于Alt BOC信号的接收和捕获的Matlab仿真结果。
The structure of the Galileo E5 signal and the principle of the new modulation method-BOC will be introduced. The structure of E5 signal will be analysed and simplified to verified the fact that the Ah BOC signal in Galileo E5 band can be approximated as a QPSK signal. At last the simulation of reception process and acquisition of Ah BOC signal in Matlab will be listed.
