Theoretical and Practical Teaching Reformation of Communi-cation Principle//ZOU Li
Abstract In this paper, the reform of theoretical and practical tea-ching in communication principle is presented. The theoretical tea-ching reforms are carried out with two parts. One is that the actual application scenarios of the communication system is brought into
the classroom teaching. And the online and offline teaching model is
adopted, which enhances the learning effect of students and make
students become the ultimate beneficiaries. Practical teaching reforms
adopts a new experimental platform, which can realize virtual simu-lation and remote control of connected hardware devices for actual system development and design, which greatly improves students practical ability and stimulates students learning motivation.
Key words communication principle; teaching reform; theoretical teaching; practical teaching; blended leaning; experimental software;

通信原理课程是通信、电子、信息领域最重要的专业基础课程之一,是通信工程等专业的标志性课程。该课程也是信息与通信工程学科研究生入学考试专业课程之一,占有重要的教学地位。课程内容主要涉及信息的物理传输,以各种调制技术的分析作为主线,紧紧围绕通信系统的有效性和可靠性这对矛盾进行分析,对各种通信系统的性能指标进行评价与比较。该课程作为通信工程专业的核心与标志性课程,有较强的理论基础性和工程应用特点。它涉及的知识面宽、概念多,并要求具有一定的数学基础。同时,该课程也是公认的“老师难教、学生难学、考试难过”的“三难”课程[1]。
通信原理主要涉及信息量的计算、信息的物理传输理论与技术。通信技术过去几十年中不断发展,在此基础上陆续形成通信的理论体系[2]。本课程以各种调制技术的分析作为主线,辅以信号的接收和同步技术,紧紧围绕通信系统的有效性和可靠性性能指标进行分析,对各种通信系统的性能指标进行分析与计算。……
