Yuxin Qin and Xinran Tao

In the communication process of Unmanned Aerial Vehicle (UAV), it will be affected by interference, resulting in performance degradation. In order to better understand its communication performance, the channel can be simulated. Firstly, this study analyzed the characteristics of UAV communication channel, described the large-scale fading, small-scale fading and interference of signals, introduced the channel modeling method, analyzed the calculation method of model parameters, and finally carried out simulation experiments. The results showed that the simulation results of the channel were basically similar to the actual results. In addition, from the perspective of anti-electromagnetic interference performance, the larger the interference to signal ratio was, the greater the symbol error rate of the channel was. The experimental results verifies the reliability of channel simulation, which can provide a good theoretical basis for UAV communication research. The channel simulation is worth further application and promotion.
