| 摘 要： | 针对卫星导航系统中BOC＋BPSK混合共用载频调制的现状,研究了基于频域平滑周期图法的BOC单频调制与BOC＋BPSK混合共用载频调制2种调制信号循环谱包络切面的特性,实现了对这2种调制信号的参数估计.仿真结果表明,基于谱相关的BOC＋BPSK混合共用载频调制时的参数估计性能与BOC单频调制时基本一致,验证了BOC信号叠加在传统BPSK导航信号上可有效实现频段共享.

| Abstract: | Aiming at the development situation of BOC ＋ BPSK hybrid modulation for modern satellite navigation system,this paper studies the characteristics of the cyclic spectrum envelope tangent plane for the single carrier frequency BOC modulation and BOC ＋ BPSK hybrid carrier frequency modulation based on the frequency smoothing period diagram. The parameter estimation for both modulation signals is realized. The simulation results show that the BOC ＋ BPSK hybrid common carrier frequency modulation based on the spectrum correlation is consistent with the single carrier frequency BOC modulation about the parameter estimation performance,and verify that superimposing the BOC signal on the traditional BPSK navigation signal will effectively realize the frequency band sharing. |
