摘要
针对无线通信实验教学受设备数量、成本、场地等因素限制,难以满足实验教学的需要的问题,提出利用大型网络仿真软件OPNET开展无线通信类课程实验的教学思路,设计了无线收发信机设置、无线管道阶段编程以及天线建模3个大项实验,使学生掌握OPNET无线网络仿真建模的一般方法。实践结果表明,基于OPNET的无线网络仿真实验不但有效弥补了实验条件的不足,也取得了较好的教学效果。
The wireless communication experimental instruments have many shortages such as scarce, expensive and large in size, which couldn＇t satisfy the need of teaching. In order to solve this problem, the method that brings OPNET simulation software to the experimental teaching is proposed. Three kinds of experiments are designed, including the wireless transceiver configuration experiment, the wireless pipeline stage programming experiment and the antenna modeling experiment. Through these experiments, the general method of OPNET simulation could be studied by the students. The practice indicates that OPNET wireless network simulation experiments can make up the drawbacks of experiment hardware environment effectively, and the teaching effect is improved.
