成对载波多址技术在靶场卫星通信系统中的应用

Application of Paired Carrier Multiple Access Technology inRange Satellite Communication System

卫星通信具有覆盖范围广、部署方便和不受地理环境限制等优点,是靶场信息通信系统的重要组成部分,但由于卫星转发器资源有限、通信保障难等原因,致使卫星通信系统应用存在一定的限制。采用将基于相关函数的成对载波多址(Paired Carrier Multiple Access, PCMA)技术应用于靶场卫星通信系统的方式,通过PCMA设备使通信双方工作在同一频段,从而节约近一半卫星转发器资源,同时实现卫星通信保障需求,具有较好的自干扰抑制能力,有效提升了靶场卫星通信系统性能。

Satellite communication has the advantages of wide coverage,convenient deployment and free from geographical restrictions,and is an important part of the range information communication system.However,due to the limited resources of satellite transponder and the difficulty of communication support,there are some limitations in the application of satellite communication system.By applying Paired Carrier Multiple Access(PCMA)technology based on correlation function to the range satellite communication system,the communication parties are enabled to work in the same frequency band by PCMA equipment,thus the satellite transponder resources are saved nearly half,the requirements of satellite communication support are met.And the proposed method has good self-interference suppression ability,can effectively improve the performance of the range satellite communication system.
