中文摘要: 战场信息中包含大量固定相关术语且快速有效传输，对信息压缩有利于快速传输，但现有的一些压缩算法针对战情报文压缩效果不是和理想. 文中介绍了LZW算法原理，在LZW算法的基础上增加了战情动态词典、重复编码器进行算法改进. 在多项改进的基础上结合FPGA的优点用硬件实现，获得了很好的效果.
Abstract:Fixed battlefield information contains a large number of related terms with fast and efficient transmission, compression is conducive to rapid transmission of information, but some of the existing compression algorithm for war intelligence and compression effect is not ideal. This paper introduces the principle of LZW algorithm, based on the LZW algorithm increases the situation dynamic dictionary, repetitive encoder algorithm is improved. In a number of improvement on the basis of combining the advantage of FPGA in hardware implementation, obtained the good effect.
