摘　　要：在无线通信中,由于散射体的存在,信号在复杂物理信道传播过程中发生多径效应,不同条件下的多径效应对信号的影响也不同。文章针对更贴合实际环境的新型圆盘模型进行研究,通过改变基站(Base station,BS)与移动站(Mobile station,MS)的距离和圆盘的半径,经过详细的仿真分析来比较对信道特性的影响,并说明该模型更适用于宏小区环境,来比较无线通信环境的变化对信道特性的影响。In wireless communications, since the presence of the scatters, a signal occurs multipath effect during propagating in the complex physical channel, and under different conditions, the multipath effect have different influence on the signal. In this paper, a novel disk channel model is considered, which is better fit for the realistic environment. By changing the distance between the base station and the mobile station and the radi- us of the disk, the changes of channel characteristics are compared in the wireless communication.
