一种三维无人机MIMO宽带信道模型

针对无人机环境特点和MIMO天线系统，建立并分析了由直射、反射和散射分量组成的基于圆筒散射三维几何传播模型，根据方位角非全向散射和俯仰角非对称分布的特点，结合无人机实际飞行参数特点，推导出简洁的闭环空时频联合相关函数，通过仿真进行了验证，分析了空时频相关特性的影响因素．

A Three-Dimensional MIMO Wideband Channel Model for the Unmanned Aerial Vehicle

Accordi Multiple-Input M ng to surroundings of the Unmanned Aerial Vehicle （UAV）in the wideband ultiple-Output （MIMO）channel, we presente a three-dimensional geometrically based cylinder scattering （GBCS）model with direct, reflective and scattering components. A closed-form joint space-time-frequency cross-correlation function is derived for the three-dimen- sional non-isotropic scattering and asymmetrical environment based on the flying parameters in practice. Simulations indicate the feasibility and validity of the simplification. The factors of the space-time-frequency correlation are analyzed in the simulation.
