针对利用平流层平台与地面基站协同为用户服务的平流层协同通信系统,本文提出利用Nakagami-m衰落信道模型描述地面节点之间信道的衰落特性,利用Lognormal衰落信道模型描述地面节点与平流层平台之间信道的衰落特性。在此基础上,利用矩生成函数匹配法( MGF, Moment Generating Function)分析了由地面用户、地面基站以及平流层平台组成的平流层协同通信系统其上行链路在采用译码转发( DF,Decode-and-Forward)协议时的中断性能,并作了仿真验证。

In the light of stratospheric cooperative communication system with stratospheric platform and ground base-station to cooperatively provide service for users,this paper proposes the idea to use Nakagami-m fading channel model in describing channel fading characteristics between ground nodes, and Lognor-mal fading channel model in describing channel fading characteristics between ground node and strato-spheric platform. Based on this and with the function matching ( MGF, moment generating function) gen-erated by moment, the outage performance of stratospheric communication system composed of terrestrial users, ground base-stations and stratospheric platforms in the decoding forwarding ( decode-and-forward, DF) is analyzed, and simulation verification also done.
