实践课程“软件无线电系统设计与验证”研究

摘要

实践课程教学是培养专业学位研究生（专硕）知识应用能力，增长工作经验，提高专业素养及就业、创业能力的重要环节。该文从实验平台建设、实验项目、实验环节和考核方式等方面，介绍了专业学位硕士实践课程软件无线电系统设计与验证的建设思路和教学经验。以无线电系统中重要的数字下变频（DDC）器设计实验为例，详细展示了课程教学过程与实验实施方法。实际教学效果表明，通过课程学习，学生掌握了现代无线电系统产品设计的一般方法和过程，提高了在实际工作中发现问题和解决问题的能力。%The primary purpose of practical course offered for professional degree graduate students (master)is to cultivate their capability of applying the knowledge in practice,to acquire the working experiences,to make them more professional and to promote the abilities suiting their employment and startup.The paper introduces the researches and experiences of the practical course,Design and Validation of Software Defined Radio System,based on the building of experimental platform,the design of experiment projects, the main links of training procedure,and the testing pattern.Moreover,the realistic teaching procedures and methods are illustrated by an example of designing a digital down converter (DDC)of radio system.The results of teaching manifest that the course could make the students obtain the basis procedures and methods of development and design for the modern wireless radio system,improve their ca-pabilities on analyzing and resolving the engineering problem met in work.
