摘要
介绍了数据压缩的现状,分析了遥测噪声数据的特点和无损压缩算法的原理。根据噪声数据特点,通过各个算法比较和相关验证性实验,提出了LZ＋ARC数据无损压缩算法,重点介绍了该无损压缩算法的原理和实现过程,并将该算法原理针对大量噪声数据进行了仿真压缩,结果表明压缩去除率可达到60%~90%。
The status of data compression is introduced, some character of telementry yawp data and the princi- ple of lossless compression algorithms are analyzed. According to the characteristics of the yawp data require- ments, some experiments have been finished. A suitable compression algorithm is found, and a new compression algorithm with LZ and ARC is designed. With many simulation works, it can be proved new compression algo- rithm＇ s compressed rate is 60% -90%.
