| 摘 要： | 针对导航信号的多径误差分析,在多径误差包络曲线分析方法基础上提出了多径误差包络期望分析方法。与包络曲线分析方法相比,包络期望分析方法能够定量分析导航信号多径误差。基于包络期望分析方法,对同码速率的二进制偏移载波(BOC)调制导航信号与二进制相位控键(BPSK)调制导航信号的多径误差进行了对比分析。结果表明,BOC调制导航信号具有更小的典型多径误差。

| Abstract: | As to the multipath error analysis of the navigation signal,based on the analysis method of plotting the multipath error envelope curve,the multipath error analysis method of calculating the expectation of multipath error envelope was presented.Compared with the envelope curve method,the envelope expectation method could analyze quantificationally the multipath error of the navigation signal.Then the multipath error of the BOC modulated navigation signal were compared with that of the BPSK modulated navigat... |
