摘要

为了实现无人机上的大容量数据业务,必须对无人机通信信道及其对OFDM通信系统的影响进行充分的研究。分析了几种场景下无人机的通信信道模型,给出了不同场景下ICI对OFDM系统性能的影响。此外,本文还分析了信道干扰与子载波间隔的关系,有助于设计人员开发新的信道均衡和消除信道干扰的方法。

Impact of Doppler on High Speed UAV OFDM System
To implement the large-capacity data traffic on Unmanned Aerial Vehicle (UAV), sufficient research on UAV communication channel and its effect on OFDM communication system must be performed. This paper analyzed the communication channel models of UAV under several scenarios, and gave the impact of ICI on performance of OFDM system in different scenarios. Moreover, this paper analyzed the relationship between ICI and subcarriers interval, which can help designer to develop new way of channel equalization and eliminating ICI.
