安捷伦仿真软件和仪器在通信原理实验中的应用

Application of communication principle experiment based on Agilent software and instrument

现代通信信号体制采用多进制调制来提高信息传输的有效性。能够让学生直观地理解多进制信号体制,熟悉通信仿真软件和射频仪器操作,激发学生学习兴趣是通信原理实验课程改革的一个方向。通过介绍基于安捷伦(Agilent)仿真软件和仪器搭建16QAM信号产生和分析平台的操作步骤、星座图编码方式设置、测试结果等,阐述了怎样在实验教学中让学生动手实际产生多进制信号的方法和实践操作过程。提炼了实验教学思想和方法,也对通信原理实验教学改革具有一定的参考价值。

Modern communication signal system uses multiple modulation to improve the efficiency of information transmission. To enable students intuitively understand the multiple modulation signal system and stimulate students' interest in learning,the direction of the reform of communication principle experiment course includes skillfully operating of communication simulation software and radio frequency instrument. This paper demonstrates how to introduce the operation steps of the 16 QAM signal generation and analysis platform,the arrangement of the coding method and the test results based on Agilent software and instrument. Methods and practical operation process for students to generate multiple modulation signal are presented in the course. The thoughts and methods of laboratory teaching distilled in this paper may be a helpful reference for the reform of laboratory teaching.
