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。 In this paper, a set of novel parameters for describing the propagation environment of a community is proposed. They are all clearly defined and have their own physical meanings. After the introduction of this set of parameters and elliptic model, the thesis uses them to calculate the arrival distribution and diffusion parameters of multipath signals. Calculations are performed in time domain and airspace, respectively. The results were discussed, and the practical value of this parameter in the simulation was initially confirmed. Finally, some possible further work directions were proposed.
