| 摘 要： | 针对无人机环境特点和多天线系统,建立了基于圆筒散射的三维几何无人机MIMO宽带信道模型。该模型不仅由直射、反射和散射等多种分量组成,还考虑了飞行参数、散射环境以及天线间距等因素。根据地面控制站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,并通过仿真进行了有效性和可行性验证。

| Abstract: | According to the environment of Unmanned Aerial Vehicle(UAV) in wideband Multiple-Input Multiple-Output(MIMO) channel,a three-dimensional geometrically based cylinder scattering(GBCS) model with line of sight,specular and diffuse components is presented.Parameters such as flying parameters,scattering environment and distance between antennas are considered in this model.A simple closed-form joint space-time-frequency cross-correlation function is derived according to the non-isotropic scattering of azimuth ... |
