数据通信中文本文件无损压缩算法的实现

摘要

针对目前人们对数据通信的需求日益增加，由于种种原因，数据通信的速率还不够高，数据通信的低速率已经成为数据通信系统的瓶颈。在摱滩ǖケ叽⒒畔⒋湎低硵中，作者利用基于字典的LZW无损压缩算法(对象是文本文件)，实现了用软件的方法将通信速率提高了大于300％的实际效果。编程语言采用VC++，并制作成.DLL文件。%In allusion to increasing need for data communication nowadays,the speed of data communication is not enough high because of many kinds of reasons. The low speed has become bottle-neck of data communication system. In the system of "unilateral-band computer information transmission" ,we achieve to increase trebly the communication speed of that. The language of programming is VC++,then execute DLL files.
