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“短波单边带微机信息传输系统”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.
