几个BOC 信号的分析例程，全球卫星导航系统将普遍使用BOC调制信号作为扩频测距信号，BOC信号号自相关函数呈现多个相关峰，传统扩频接收机所用的延迟锁定环（DLL）无法对该信号正确地进行码相位的 -Several BOC signal analysis routines, the global satellite navigation system will generally use the BOC modulation signal as a spread spectrum rangin

gps延迟锁定环中对热噪声的模拟，考虑了热噪声对跟踪精度的影响，很不错的-gps delay locked loop in the thermal noise of the simulation, taking into account thermal noise on the impact of tracking accuracy, very good
