摘　　要：BOC调制信号应用在卫星导航系统中有很多优势,其具有良好的抗多径、抗干扰性能和很高的研究价值。针对目前国内没有功能完善的BOC调制信号发生器,无法深入展开BOC调制信号相关研究的现状,开展了BOC调制信号发生器的研究并设计了一种基于FPGA的BOC调制信号发生器。详细介绍了BOC调制信号发生器的系统组成,各个模块的实现方式,指出了实现的关键技术。使用频谱仪对BOC调制信号发生器进行了测试,验证了其产生BOC调制信号的正确性。BOC modulated signal has a lot of advantages when it is used in satellite navigation system,it has good anti-multipath and anti-jamming performance,and thus has very high research value. Aiming at the present condition that there is no BOC modulated signal generator with perfect function at home so that the related research of BOC modulated signal cannot develop deeply,the researches about BOC modulated signal generator are carried out and a kind of BOC modulated signal generator based on FPGA is designed.The constitution of the system and the realization way of each module are introduced in detail,and the key technique is pointed out.Finally,the BOC modulated signal generator is tested by spectrum analyzer,which verifies that the BOC modulated signal it generates is correct.
