Abstract: We analyze Wireless Communication System course characteristics seriously, and find its difficulty points and focal point. Aiming at the key points and difficulties of this course that we have discovered, we execute a series of teaching reform of Wireless Communication System course. Our school has engineering professional background. In order to meet characteristics of our school, we strengthen the learning of practical application examples of wireless communication engineering, and innovative teaching models, teaching content, and assessment methods. Proved by teaching practice, teaching reform can greatly improve the teaching effect. Interests on this course of students have been improved greatly, and our students' ability of analyzing and solving problems has been also improved greatly. In general, teaching effect of our school Wireless Communication System course has been greatly improved through this teaching reform. We also put forward some ideas for follow-up education reforms of Wireless Communication System course.

《无线通信系统》课程是沈阳理工大学信息科学与工程学院通信工程专业大学三年级本科生必修的一门重要专业课程,主要讲述无线通信系统概述、无线频谱划分、无线通信系统模型分析方法、电波传输与短波通信系统、微波中继通信系统及卫星通信系统等内容。此门课程所讲授的教学内容既是通信工程专业本科学生必须掌握的专业理论知识,又是实际通信工程设计与集成的基础,因此该门课程在通信工程专业的本科教学体系中具有较为重要的地位[1-3]。但是,由于无线通信理论及技术的快速发展,此门课程具有理论性较强、对学生抽象思维要求较高的特点,并涉及较多繁杂的数学公式,对学生数学基础、算法理解及具体工程实践应用能力都有很高的要求,因而在实际的教学活动中对讲授此门课程的教师及学习此课程的学生都具有一定的挑战性[4-6]。……
