摘　　要：随着移动互联技术的发展,人们在日常生活和商务活动中,越来越希望能够以移动的方式灵活地接入因特网。2002年11月,IEEE802标准委员会成立了802.20——移动宽带无线接入(MBWA)工作组,致力于为移动用户开发一个新的标准。以IEEE802.20物理层关键技术为研究对象,从一般的无线信道模型入手,通过对MIMO信道进行分析,以现有MIMO信道模型和建模方法为基础,给出一个基于IEEE802.20协议的信道模型,并在此模型上进行仿真与性能分析,得到模型的频域和时域特性,从而证明给出的信道模型和仿真方法能够准确地描述IEEE802.20的信道特性。With the development of mobile communication technologies,the people increasingly hope to have an easy access to the Internet by mobile mode in their daily life and business.In December 2002,the IEEE Standards Board approved the establishment of IEEE 802.20,the Mobile Broadband Wireless Access（MBWA） Working Group,which is engaged in the development of a new standard for mobile Internet users.With the key technology for Physical Layer（PHY） of IEEE 802.20 standard as the focus,the paper discusses several functions of the channel in signal transmission,and then analyzes the MIMO channel.Having summarized the existing MIMO channel models and the modeling methods,the author proposes a comprehensive channel model based on IEEE 802.20 for simulation and performance analysis.Experiment result shows that,the range of frequency and time in simulation is identical with that in theoretical analysis,and the channel model and simulation methods proposed in this paper could give an accurate characteristic description of the IEEE 802.20 channel.
