1、多媒体技术课程设计报告二九 二一 学年第 二 学期应用技术学院课程设计报告书课程名称： 多媒体技术 班 级： 09级网络工程 学 号： 姓 名： 指导教师： 二一 年 六 月1.需求分析1.1课程设计题目信源与信道编/解码练习。1.2课程设计要求 1)要求利用程序设计软件(如VC、Java、Matlab)制作一个能完成信道编/解码(海明/CRC码)，信源编/解码(如行程编码)软件。2)基本要求为编制软件至少能根据所输入的数据完成信源、信道编解码，其中信道编码要求能产生1-2位随机错误，且能纠1位错，最后是能读取txt文件，或者直接读取图片来完成，如能对视频完成则更佳。3)编写的软件编译后能直接

2、运行，验证编/解码效果，否则无效。 1.3系统功能需求分析 操作环境（软件、硬件及条件） Windws 9x/NT/2000/XP/2003 NetBeans IDE 6.8系统功能此软件是在JAVA平台下编写的 ，能根据所输入的数据完成信道（海明码）、信源编解码（行程编码），其中信道编码（海明码）能产生1位随机错误，且能纠1位错，最后是能直接读取图片或txt文件来完成。用户操作流程 编 码： 解 码： 2.概要设计系统总体框架： 3.详细设计本次课程设计中我主要负责界面设计和行程编码，故作以下详细介绍。3.1界面设计界面设计如图3-1所示：图3-1界面设计代码如下：package DMTco
