摘要
文中提出了一套新颖的用于描述小区传播环境的参数 ,它们定义明确 ,都有自己所代表的物理意义。论文在介绍了这套参数和椭圆模型后 ,利用它们对多径信号的到达分布 ,扩散参数作了计算。计算分别在时域和空域上进行。并对结果作了讨论 ,初步证实了这套参数在仿真中的实用价值 ,最后 ,提出了可能的进一步工作方向。
A novel group of parameters for microcell propagation environments are proposed. They are clearly defined and useful for qualifying the real wireless channels with non-uniformly distributed scatterers. We explored them to calculate ToA (Time of Arrival) and AoA(Angle of Arrival) distribution .The r.m.s. delay spread had angular spread are also been investigated , which prove the usefulness of the parameters in channel simulation work.
