基于MATLAB的通信系统仿真教学研究

The Research of MATLAB Based Communications Systems Simulations Teaching Method

针对通信原理类课程的教学特点以及基于硬件实验教学过程中存在的问题,讨论了将MATLAB软件引入到通信系统仿真教学的必要性。以单/双极性不归零码为例,分别从理论分析和编程仿真两个方面给出了两种码型在高斯信道中的误码性能分析,并给出了仿真结果。将MATLAB软件引入到通信系统仿真教学中,可增强所学理论知识点的直观性和生动性,增加学生的学习兴趣,提高了学生的知识理解能力和编程能力,改善了教学效果。

According to the teaching property of communications principles and the difficulties in the hardware based experiments teaching,we have discussed the necessaries to introduce the MATLAB software into the communications systems simulations courses.Taking the single/double polarity not return zero(NRZ)code as an example,we derived the bit error rate performance by considering the two codes over the additive Gaussian channels,and provided the corresponding simulation results.By introducing MATLAB into communications systems simulations,it can enhance the intuition and vividness of the theoretical knowledge,increase the students’learning interest and programming ability,and raise the teaching effects of courses.
