| 摘 要： | 信道模型对分析智能天线系统的性能是非常重要的。针对基于(散射体)几何分布的单反射椭圆模型(GBsBEM)在计算机模拟时参数难以确定的不足,本文结合UMTS-IMT-2000推荐的信道模型,提出了一种新的空时信道模型,并给出了计算机模拟方法:以GBSBEM模型为基础,吸收UMTS-IMT-2000推荐的信道模型的时延和功率方面的参数并考虑GBSBEM模型中DOppler效应对信号幅度的影响,模拟空时Rayleigh信道。在这一方法的基础上,又提出了多用户空时信道简化模型以及模拟方法。计算机仿真结果表明,所提出的信道模型计算机模拟方法是可行的。

| Abstract: | Channel model is essential to performance analysis in smart antenna systems. Parameters are not easily determined in GBSBEM model, which is commonly used in smart antenna systems. This paper pres-ents a new space - time model, which combines GBSBEM model and the mobile model suggested by UMTS-IMT- 2000. Based on GBSBEM model, this paper puts forward model absorbed some parameters suchas time delay and power in UMTS - IMT - 2000 suggested model. At the same time, Doppler effect is also taken into account. The detailed simulation steps are included in this paper. Based on the presented mod-el, multi - user space - time model is also presented. Computer simulation shows that the presented model is feasible in smart antenna systems. |
