MATLAB在信源编译码技术教学中的应用研究

Research on Application of MATLAB to Information Source Encoding and Decoding Technology Teaching

针对“通信原理”课程的重要教学内容——信源编译码技术具有概念抽象、理论性强、应用方法灵活等特点,以培养应用型人才为出发点,对该课程的教学改革进行了研究,引入MATLAB软件对重要的教学内容进行建模仿真和性能分析,在信源编译码技术教学中应用MATLAB软件演示了两种主要的信源编译码方法——脉冲编码调制和增量调制的程序和波形,提高了教学直观性及趣味性,促进了学生对信源编译码的基本方法和主要特点的理解和掌握,取得了较好的教学效果。

and complicated.To keep pace with the trends of application-oriented talents cultivation,the author conducted teaching reform in Communications Theory course and applied MATLAB simulation to important teaching contents.When teaching information source encoding and decoding schemes,the author performed MATLAB simulation demo of two primary information source encoding and decoding schemes,that is,Pulse Code Modulation and Delta Modulation,which improve teaching intuitiveness and teaching quality a lot.
