摘要 我们研究了Compass,GPS和Galileo系统的兼容情况,分析了Compass系统各频段信号的功率谱密度以及与GPS和Galileo信号的重叠情况,然后在考虑星座和多普勒影响的前提下,以谱分离系数和等效载噪比衰减作为系统兼容性的评估标准,仿真并分析了Compass,GPS和Galileo系统的相互干扰程度.基于分析结果从信号兼容性、互操作性和信号性能等方面出发,对Compass信号体制的设计提出了建议. This paper analyses the compatibility of Compass, GPS, and Galileo systems. Firstly, the spectrum of the Compass signals and the overlap of these systems are analyzed. Then the spectral separation coefficient and equivalent degradation of carrier-to-noise ratio are used as criteria to evaluate compatibility among these navigation systems. The effect of constellation and Doppler are taken into consideration. The simulations of the intersystem interferences are performed for signals where Compass, GPS, and Galileo are sharing the band. At last, this paper presents suggestions about the signal structure design for Compass system from the compatibility, interoperability and navigation industries point of view.
