摘要/Abstract

摘要： 针对无人机MIMO三维单跳同心椭圆环(GBSBCER)信道模型,给出无人机空时频信道相关函数的简要形式,推导了归一化无人机MIMO信道相关矩阵,应用该矩阵分析了天线结构、飞行距离以及散射体分布等参数对无人机MIMO信道矩阵条件数和容量等信道特性参量的影响。仿真表明,通过合理布局天线,调整飞行参数可以提高无人机MIMO通信性能,为实现MIMO技术在无人机通信系统的应用提供理论基础。

Abstract: The simple form of UAV space-time-frequency channel correlation function was presented based on the three-dimensional geometrically based single bounce concentric elliptic ring scattering (GBSBCER) channel model of Multi-Input Multi-Output（MIMO）for Unmanned Aerial Vehicle (UAV). The analytic formula of UAV-MIMO normalized correlation matrix was deduced. The effect of antennas structures, flight distance and scatters distributing on the characteristic parameters such as the condition number of UAV-MIMO channel matrix and the channel capacity were analyzed by this formula. The simulation results show that, the performance of UAV-MIMO communication can be improved by reasonably arranging the antennas, adjusting the flight parameters, which lays a theoretical foundation for realizing the application of MIMO technology in UAV communication system.
