Coexistence Analysis Between Compass RDSS Services And Common Mobile Communication System

Beidou satellite navigation system and mobile communication system are both in the rapid development,and they are also facing some problems:on one hand,the business development and system upgrade of the Beidou satellite navigation system need to expand the spectrum resources;on the other hand,with the development of mobile communication system,it is also facing the problem of spectrum resources shortage.There is reason to believe that,with the development of the Beidou satellite navigation system and mobile communication systems,there will be more scenes of coexistence between them in the future.According to this basis,the main contents of this thesis are:The typical interference scene and the type of the signal interference between Beidou satellite navigation system and common mobile communication systems;Analysis of related technology of interference coexistence between systems,and giving out the general calculation process and analysis methods are used in the interference scene which are combined with the contents of this paper;The spectrum characteristics,the interference threshold and other parameters of GSM,CDMA,WCDMA mobile communication system and Beidou satellite navigation system;Using with the link budget methods to analysis the interference coexistence betweent satellite navigation system and common mobile communication systems,giving out the spectrum characteristics of the Beidou transmitter when no signal interference between systems achieving at different distances isolation target;Using with the Monte Carlo system-level simulation methods to analysis the interference coexistence betweent satellite navigation system and common mobile communication systems,and summarying the different interference coexistence which influenced by the different spectrum emission pattern.Ten giving out the spectrum template scheme of the Beidou uplink transmitter which can coexist with all of the common mobile communication systems.The research of this paper is on the key period of the development of the Beidou satellite communication system,it has important strategic significance.At the end of the article,the full text is summarized,and the future research content is given according to the present situation and the feasibility of the technology.
