在本文中,一个三维(3-D)的几何模型被认为是同时描述多径波的到达角(AoA)的方位角和仰角平面。该模型适用于具有低MS天线和高架基站(BS)的宏蜂窝环境,其中散射体分布在具有小区半径和BS高度的圆柱体中。从移动的站(MS)的角度来看,提供的概率密度函数的封闭形式的表达式。结果表明,方位角AoA取决于基站和移动台之间的距离与小区半径的比值,而仰角AoA则取决于基站的高度、小区半径以及基站和移动台之间的距离。通过蒙特-卡罗仿真验证了该模型的准确性。
In this paper, a three-dimensional (3-D) geometric model is considered to simultaneously describe angle of arrival (AoA) of multipath waves in the azimuth and elevation planes. The model is suitable in a macrocellular environment with a low MS antenna and an elevated base station (BS), where scatterers are distributed in a cylinder with the radius of the cell and the height of the BS. Closed-form expressions for the probability density functions in the angles are provided as seen from the mobile station (MS). Results show that the azimuth AoA depends on the ratio of the distance between the BS and the MS to the radius of the cell whereas the elevation AoA depends on the height of the BS, the radius of the cell and the distance between the BS and the MS. Monte-Carlo simulations are performed to examine the accuracy of the proposed model.
