为了解决诸如沙漠、戈壁等广袤荒漠场景集团车辆通信问题,提出了基于卫星通信和基于高空平台通信 2 种车辆间组网模型,并给出了这 2 种模型的系统框架和组网模式. 在基于卫星通信模型中,所有车辆均配备车载“动中通”卫星通信终端,车辆间通信信号由卫星转发. 在基于高空平台通信模型中,装载基站设备的高空平台形成了空中基站,车辆使用普通地面移动通信设备即可通信. 此外,对路径损耗、链路损耗和系统容量等关键参数进行了计算. 分析结果表明,所提出的 2 种模型能够满足所述场景车辆间的通信需求.
In order to solve the communication problems of group vehicles such as Desert and Gobi, the paper proposes two kinds of inter-vehicle network model based on satellite communication and high-altitude platform communication, and gives the system framework and networking mode of these two models. Based on the satellite communication model, all the vehicles are equipped with satellite communication terminals, and the communication signals between the vehicles are forwarded by the satellite.In the communication model based on the high-altitude platform, the aerial platform loaded with base station equipment forms an air base station, a vehicle Using ordinary terrestrial mobile communication devices to communicate.Moreover, the key parameters of path loss, link loss and system capacity are calculated.The results show that the proposed two models can meet the communication needs of the scene vehicles.
