Abstract

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.
