摘要
无人机飞行过程中,不同飞行状态具有不同的信道特性,从而会影响数据的可靠传输。为分析这一影响,文章基于Bello提出的WSSUS信道模型,在分析无人机通信信道特性的基础上,得出无人机通信信道模型;随后将无人机飞行过程划分为起飞/降落、途中飞行和空中盘旋三个状态,并分别讨论三种状态下的信道参数;最后通过仿真,对三种状态下数据传输的误码率进行比较,分析影响数据可靠传输的主要原因。
Different flight states of UAV have different channel characteristics,which will influence the reliable data transmission.In order to analyzing the influence,model for UAV communication channel was derived in this paper by analyzing channel characteristic of UAV and basing on Bello s WSSUS(wide-sense stationary uncorrelated scattering) channel model.The flight process of UAV is divided into three states: taking off and landing,en-route,circled,and channel parameters of each state are discussed.Finally,the B...
