摘　　要：针对差分跳频系统构建了无线衰落信道的抽头延时模型,在此基础上比较了衰落信道的几种仿真方法,并在MATLAB仿真环境下用AR模型对信道进行仿真。仿真结果验证了模型的正确性,同时表明基于AR模型的方法很好的反映了信道的统计特性,便于计算且适用于复杂环境的建模。A tap-delayed model of wireless fading channel simulation for DFH system is presented. Based on it, AR model is selected for channel simulation in MATLAB after comparing with other two methods. The simulation results admit the model proposed and show that AR method describes the statistical characteristic of the channel adequately. Besides, it is compatible with complex environments and enjoys acceptable computational complexity.
