“信息论基础”实验教学内容仿真系统
|
摘要
为了更好地展示"信息论基础"课程的重要性,使学生理解与掌握该课程的主要内容,分析并设计基于MATLAB的信息编码软件仿真系统。以通信工程信息处理理论中的信源编码为主线,建立容易理解且容易操作的模块式仿真教学平台。采用MATLAB中图形用户界面,设计操作按钮和输入文本等界面,通过软件编程可以实现信源压缩编码方法中的香农信息编码、离散费诺编码和霍夫曼最佳编码以及连续信源编码方法中的均匀信息编码与非均匀量化编码。实验系统的工作参数可以人工调整,根据参数的不同自动发生变化,方便学生全面观察通信系统工作过程。该仿真系统不仅能模拟信源、信道等各个部分的工作过程和结果,还能对过程和结果进行分析。
In order to make students recognize the important value of"information theory"course,understand and grasp the important content of course,a source encoding software system based on MATLAB is designed. Taking the information theory knowledge system of communication engineering as the main line,the comprehensive modular practice teaching platform is constructed. Using graphical user interface,the paper set the text input box and button operation,achieved Shannon encoding,Feno encoding and Huffman encoding of discrete signal source encoding method and uniform quantization encoding,non-uniform quantization encoding of continuous source encoding method. The parameters of the experimental system can be adjusted manually and automatically changed according to the parameters. It is convenient for students to observe the working process of the communication system comprehensively. The simulation system can not only simulate the process and results of each part of the source,but also analyze the process and the result.
