| 摘 要： | GPS采用了一种新的信号形式,其关键技术为BOC(Binary Offset Carrier)调制.基于对GPS M码信号BOC调制的定义与功率谱研究,针对其采用的BOC(10,5)调制方式进行了信号仿真,进一步对其频谱与自相关函数进行了仿真,并针对其特性进行了分析,同时与现在的军用P码信号性能进行了对比,从而得出GPS现代化采用BOC调制的M码信号的优势所在.

| Abstract: | Binary Offset Carrier(BOC) modulation is the key to the new signal form in the GPS.Based on the research on the definition and the power spectrum density(PSD) of BOC-modulated signal,the BOC(10,5)-modulated signal are simulated at first.When the PSD and the autocorrelation function(ACF) are simulated,the characteristics of PSD and ACF are analyzed at the same time.Compared with the P-code the current military signal,the merits of M signal that using BOC modulation can be concluded in the end. |
