摘要
介绍了使用MATLAB模块仿真的方法开发GMSK系统误码率测试实验、各种数字基带信号功率谱密度分析实验。该方法不仅可以完成对通信系统各模块的仿真,通过对不同模块函数的组合调用,还可以实现对整个系统的仿真。在通信原理课程教学过程中,将仿真实验和电路实验系统结合使用,有效地弥补了电路实验系统的不足。
In this paper, experiments development in course of communication theory to test error probabilities for GMSK system and to analyze power spectral density for digital base--band signals are presented, the method is based on MATLAB simulation. It can be used to simulate not only the units of communication system, but also whole communication system combined by different units. These simulation experiments have been used in the process of teaching, the result appears that it is an efficient way to make up shortages of traditional communication circuit experiments svstern.
