本文深入研究了宏蜂窝环境下移动的信道的空间特性，假设移动的站（MS）周围存在高斯分布的散射体。最近提出的偏心散射物理信道模型是用来推导概率密度函数（pdf）的到达角（AoA）的基站（BS）在封闭的形式，可以进一步用于波束宽度设计的目的。宏小区环境的三个主要场景强调模拟现实情况。对高斯分布散射体的AoA统计进行了研究，并进行了适当的修正。仿真和理论结果表明，该模型接近真实的环境。
This paper studies intensively the spatial characteristics of the mobile channel for macrocellular environment assuming Gaussian distributed scatterers around the mobile station (MS). A recently proposed eccentro-scattering physical channel model is used to derive the probability density function (pdf) of the angle of arrival (AoA) of the multipaths at the base station (BS) in closed form which can be used further for beamwidth design purposes. Three main scenarios of macrocell environments are emphasized to simulate realistic situations. Previous work on the AoA statistics for Gaussian distributed scatterers is investigated and appropriate corrections are made. Simulation and theoretical results are presented, which show close proximity of the proposed model to real environments.
