Abstract
With the application of various new mission loads in unmanned aerial vehicle (UAV), how to improve the communication quality of UAV data link has become a widespread concern. With the rapid development of UAV, multi UAVs cooperative self-organizing network can accomplish tasks more reliably, efficiently and economically than a single large UAV. This paper analyzes the characteristics of mobile self-organizing network composed of multiple UAVs, and focuses on how to improve the communication quality of UAV network. After analyzing the technical principles and system models of multiple input multiple output (MIMO) and orthogonal frequency division multiplexing (OFDM) technologies, a MIMO-OFDM communication system is constructed. The simulation results show that the application of MIMO-OFDM technology in UAV communication network can effectively improve the data transmission ability.
