摘　　要：提出一种基于Matlab的无线衰落信道教学演示平台。该平台首先引入不同类型调制信号通过无线信道环节,让学生直观地了解信道衰落对信号产生的失真影响;然后讲授不同信道衰落的统计特性及模拟产生方法;最后利用数值仿真获得不同通信系统性能。教学实践表明,该平台加强了学生对无线信道特性及对通信系统影响的理解,也调动了学生编程开发无线信道模型的积极性,为进一步学习通信理论奠定了基础。A novel demonstration platform for teaching wireless channel base on Matlab is proposed. The platform introduces the part of different modulation signals passing the wireless channel. The platform can help students to understand the distortion of channel fading to the transmitted signals. After analyzing the characteristics and simulation methods of different fading, it gives the performance of difficult modulation systems by numerical method. The teaching practice proves that the demonstration platform enhances the students＇ understanding of channel knowledge and mobilizes their enthusiasm to develop new channel models, and it lays a foundation for further studying the communication theories.
