摘要
RAR编码具有较高的压缩率,其在信息存储、信息管理、通信及保密方面得到广泛使用。在实际应用中,由于工作环境的复杂多变,数据中往往含有误码,因此快速准确地恢复这些RAR编码数据,尤其是"固实"编码的数据,必须从RAR的具体编码特点和编码机理入手。首先按照RAR的编码分类,从实际码流中得出了RAR编码的两个特点,然后重点分析了"固实"编码的特点,研究了其具体编码机理,为设计"固实"编码的纠错与容错译码算法提供了依据。
RAR coding has a higher compression ratio, its information storage, information management, and confidentiality have been widely applied, In practice, because of the complicated and ever- changing work environment, data often contains a bit error, so fast and accurate restoration of these RAR encoded data, in particular, are"solid reality" encoded data, is necessary to RAR specific coding and coding features of the mechanism. Start with the RAR coding classification, and then from the actual code stream obtained RAP, format encoded both features, the focus of analysis of the"solid reality" encoding features of the specific coding mechanism for the design of"solid is"error - correcting codes and fault - tolerant decoding algorithm provides a basis.
