摘要
星地融合网络可以提供天、空、地、海立体全场景信息覆盖,满足用户多样的业务需求。针对星地融合网络,提出了基于覆盖概率的星座数和基站数的分析模型(AMCP)。该模型为星地融合网络的上行链路覆盖概率提供了分析方法。表述卫星星座数和基站数对用户信号的干扰,构建满足用户覆盖概率条件下的卫星星座数和基站密度的表达式。通过仿真分析了卫星星座数和基站密度对覆盖概率的影响,仿真结果为设计星地融合网络提供分析基础。
The integrated terrestrial-satellite network can provide the information coverage of all scenarios including space,air,ground,and ocean and can meet the diversified service requirements of the customers.Therefore,analysis model of constellation size and terrestrial base station density-based coverage probability(AMCP)is proposed.It presents an analytic approach for the uplink coverage probability in terrestrial-satellite network.In AMCP,firstly,the interference of the number of satellite constellations and base stations to the user signal is described,and then the expression of the number of satellite constellations and base station density satisfing the user coverage probability is constructed.Finally,the influence of satellite constellation number and base station density on coverage probability is analyzed by simulation,and the simulation results provide an analysis basis for the design of integrated terrestrial-satellite network.
