无线/移动通信技术是网络与通信课程体系的核心与基础。随着网络与通信领域的迅猛发展,无线/移动通信技术以前所未有的广度与深度渗透于当代网络应用的各个分支,使过去以理论分析为主的传统教学方法越来越准以适应技术发展的需要,亟需探索新手段和新方法。在分析学生掌握无线/移动通信课程知识的关键障碍的基础上,提出数值仿真实验与模型分析相结合的新教学方法,其实质是以计算机软件为工具,实现对典型信道及其信号环境、传输编码方‘案、网络等实体的建模,并在此基础上通过数值计算来展示无线移动通信各种技术方案的特点,再结合模型的理论分析为学生准确理解相应的知识建立坚实的基础。分析了该教学方法的特点,以MIMO方案的教学为例详细阐述具体案例,并据此体现该方法较之传统教学方法的独特优势。
Wireless/Mobile communication technique is the core and foundation to the courses of network and communications. With rapid development in network and communieatior, wireless/mobile communication technique widely and deeply diffuses into all branches of contemporary network applications, as a result, the traditional teaching method which focuses on theoretical analysis is more and more difficult to catch up with the requirements from industries. Thus, innovative teaching methods are strongly needed. On b~sis of analyzing the dominating hardness for undergraduate students to master the knowledge in wireless/mobile eommu,aication techniques, a simulation experiment and model analysis integrated method is raised to teach the course in which essence is to model the typical fading channels, transmission schemes and networks etc. by means of computer software to present the schemes' remarkable properties via numerical computations and theoretical analysis. The method' s characteristics and advantages are analyzed and revealed via systematic descriptions on the case of studying MIMO system properties.
