Analysis of Unmanned Aerial Vehicle MIMO Channel Capacity Based on Aircraft Attitude
Authors: , ,
Abstract: In the paper, the demand of Unmanned Aerial Vehicle Multi-Input Multi-Output (UAV-MIMO) communication are taken into consideration, four-element circular antenna array are adopted on the UAV. In order to analyze UAV-MIMO communication system, the uniform coordinate is proposed, and the three-dimensional geometrically based single bounce cylinder model (3D-GBSBCM) channel model of UAV-MIMO system based on four transmitting antennas and two receiving antennas is put forward. The methods of channel matrix factorization and channel coefficient normalization are adopted to deduce the average channel correlation matrix of UAV-MIMO. The influences of UAV attitude parameters on UAV-MIMO channel capacity are simulated and analyzed. The simulation and analysis results have good reference and application values in improving UAV-MIMO system capacity through changing attitude parameters of UAV.
