摘　　要：通信原理实验是信息类专业的实验教学必修课,在实际教学中,主要从教学内容的设置、教学手段的完善与改革、科研活动的融入等方面来思索和探讨该课程的实验教学方法,综合运用多种软件仿真平台,介绍了基于DDS(直接数字频率合成技术)的二进制CPFSK(相位连续的频移键控)信号产生及FPGA(现场可编程门阵列)实现的实验过程。实践表明,这些方法可以进一步改善实验教学效果,降低实验成本,培养学生的实际动手能力和创新能力,适应现代通信新技术的发展需求。The Communication Principle Experiment is a required course of experimental teaching for the information professional students. In the actual teaching, mainly from the setting of the teaching content, improvement and reform of teaching methods, joining of research activities, the experimental teaching methods should be thought about and explored. The comprehensive use of a simulation platform with more software, introduces the binary CPFSK （continuous phase frequency shift keying） signal generator and FPGA （field- programmable gate array） realization based on DDS （direct digital frequency synthesis technology）. The practice shows that these methods can further improve the teaching effect, reduce the cost of experiments, and train students＇ practical ability and innovative ability to adapt to the development of new technologies of modern communication needs.
