  • 摘要: 无线紫外光通信成为强电磁干扰下的有效通信手段,满足复杂战场环境下车队执行战略物资运输和弹车队隐蔽行驶时车辆间保持可靠隐秘通信的需求。在行驶中每辆车自身作为其它车辆的中继,通过多跳方式为非视线内车辆之间建立稳定可靠的通信链路。因此,基于紫外光单次散射模型,该文研究了最优多跳中继问题,理论分析了收发仰角与频谱效率的关系,依据使频谱效率最大化原则,得出最优跳数近似表达式。仿真结果表明,不同距离移位范围和不同收发仰角都对应特定的最优跳数值,与最优能量计算方法相比,最大频谱效率计算方法在小功率传输时有更好的传输能力,并且达到节约功率的需求。紫外光长距离通信时,系统性能并不随着协作中继数的增加而提高,选取合适的中继数及小发射仰角和大接收仰角的结构配置,系统可获得较高的传输能力。
