摘　　要：通信系统由不同功能模块组成.传统教学为方便学生掌握通信工程专业的知识和技能,将各门课程的实验分时段、分地点循序渐进开展,这样不利于学习者对通信系统的整体认识.针对当前通信工程专业课程实验教学的现状,以通信原理的AM、2FSK调制解调实验与光纤通信的光传输系统实验的结合为例,设计了这两门课程的综合实验,学生可利用原有的实验器材,设计更加全面的通信系统,无需另加经费即可开展综合设计性实验,这有利于加强知识之间的联系,深化对通信系统整体性的理解,提高学生的动手能力,节约实验时间及实验室建设时间.It is well-known that communication systems are composed of various function modules. In orderto facilitate students to study the knowledge and skills of major of communication engineering, the traditionalcourse experiments are made gradually, which is not benefit to guide the student to consist of the relativelycomplete communication system. Aiming at the current experimental teaching situation of communicationengineering core courses, this paper develops a synthetic experiment based on “Principle of Communication”and “Fiber Optical Communication Technology”. As an example, the experiments of AM, 2FSKmodulation/demodulation and the one of optical transmission system were synthesize, previous equipmentswere utilized to design a more comprehensive communication system to accomplish a relative complicateexperiment without extra funds. It can help students to reinforce the links between diverse knowledge, to gaina deeper understanding of theory about the whole communication system, and to improve operational abilityand save time of experiments ＆ the laboratory construction.
