A New Simulation Method for UAV Communication Channels Based on GPUs

Xujun Hu, Xiaomin Chen, Qiuming Zhu, Weizhi Zhong, and Bin Chen
Abstract—In this paper, an unmanned aerial vehicle (UAV) communication channel model is established by considering the propagation path loss, shadowing, and multi-path fading. Moreover, an efficient generation method for Gaussian random processes based on sum of sinusoids (SoS) theory is presented and is easy to realize by a graphics processing unit (GPU). Based on the proposed method, a new real-time generation method for multi-path shadowing composite fading is designed and implemented. The implementation results show that the proposed approach enables the easy generation of multi-path shadowing composite fading while reducing the processing time. Meanwhile, the impacts of flight altitude and communication scenarios on the performance of the UAV communication system are discussed. The results of this paper should have significant application value in UAV communication channel simulation.

Index Terms—UAV communication channel, SoS, GPU, channel simulation.
