汉明码编译码系统综合实验案例设计

Design of Comprehensive Experimental Case of Hamming Coding and Decoding System

针对“信息论与编码”课程中,信道编码知识内容较为抽象,理论难以结合实际这一问题,设计了针对音频信号的汉明码编译码系统综合实验教学案例。详细阐述了案例设计思路、汉明码的编译码原理,给出了案例实现的流程,分析了案例的Matlab仿真结果。案例旨在提高学生学习的兴趣与主动性,让学生通过对比汉明码编译码前后的音频效果,直观地理解并掌握汉明码编译码的基础理论知识。该案例为“信息论与编码”课程的实践教学提供了参考。

In the course of Information Theory and Coding, the knowledge of channel coding is abstract, and it is difficult to connect theory to practice. To address this problem, this paper designs a practical teaching case of Hamming coding and decoding system for speech signal. This paper elaborates the case design idea and coding and decoding principle, describes the case design process and implementation, and analyzes the Matlab simulation results. The case aims to improve students′ interest and initiative in learning, and intends to help students intuitively understand and master the basic theoretical knowledge of Hamming codec by comparing the speech effects before and after Hamming codec. This case provides a reference for the practical teaching of Information Theory and Coding.
