摘要
针对无人机通信信道的特点和要求,提出了一种无人机信道模型。通过分析无人机通信信道的组成,将信道按照无人机的飞行状态划分为3种主要状态,最后通过实验给出了无人机在不同飞行状态下误码率性能和的仿真结果,并将此结果与计算机模拟该无人机信道下的仿真结果相比较,得出在进行无人机信道编码的仿真研究中应用该信道模型的具有可行性和重要意义。
According to the characteristics of unmanned aircraft vehicle （UAV） communication channel, a communication channel model of UAV was described. The components of UAV communication are analyzed. According to the situation of flight, the channel is divided into three major scenarios. Then numerical simulation of UAV communication channel has been done by some experiments, then compared it with the simulation result by using computer. The model built in this paper has feasibility and great significance to study the performance simulation of UAV communication channel coding.
