摘要
传统通信星座构型设计只针对系统覆盖特性选择合适的方案,不能准确反映系统的通信需求,造成资源浪费。根据多包接收的SINR捕获模型,分析宽带通信体制与构型设计及卫星运动时可通信范围等参数间的联系,并在考虑多包接收制约后对星座构型设计进行改进。该设计约束的引入,可使构型方案更好地满足系统通信需求。
Only the coverage capacity is considered in the traditional communication constellation design,which cannot reflect the requirements of communication systems and maybe cause a waste of satellite resources.The SINR capture model of multipacket reception is introduced to clarify the relationship of wideband communication systems,constellation design and communication zone while satellites are moving,and the polar constellation design scheme under the constraint of multipacket reception is improved.Constellations more suiting communication systems can be gained under such constraint.
