关于CCSDS无损数据压缩建议的初步研究

A Preliminary Study of CCSDS Lossless Data Compression Proposals

无损数据压缩是航天空间任务的重要业务 ,在商用和计算机通信中也占有越来越重要的地位。对 CCSDS(Consultative Committee for Space Data Systems)建议的无损数据压缩的基本原理、编解码方法、系统实现、压缩性能进行了分析研究。对 CCSDS的无损数据压缩建议在空间及其它领域的应用提出了初步看法 ,并指出了扩展和进一步研究的建议。

Lossless data compression is one of the major services in space flight mission.It also plays an important role in commercial and computer communication.Based on the preliminary study of CCSDS(Consultative Committee for Space Data Systems)Lossless Data Compression Recommendation,this paper discusses the principle of lossless data compression,the coding and decoding methods,its implementation and resulting performance.The paper also gives some personal ideas about the CCSDS Lossless Data Compression Recommendation's application in space and other fields and further research.
