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。
Aiming at the stratospheric cooperative communication system which uses stratospheric platform and terrestrial base station to serve users, this paper proposes to use Nakagami-m fading channel model to describe the fading characteristics of channels between terrestrial nodes. Lognormal fading channel model is used to describe terrestrial nodes and stratospheric platform The fading characteristics of the channel between. Based on this, the MGF (Moment Generating Function) is used to analyze the stratospheric cooperative communication system composed of terrestrial users, terrestrial base stations and stratospheric platforms. When the uplink is in the form of Decoder and Forwarding (DF) -and-Forward protocol interrupt performance, and made a simulation.
