Text is a kind of very common resource in digital library , and lossless techniques play an important role in compressing text . starting from the shannon ' s entropy theory , we analyze the lossless compression algorithms , and implement arithmetic coding algorithm in c . in the experiments , we compare four different lossless compression algorithms by their performances such as compression rate , compression rate tendency with the length of data , stability , and complexity , using 35 groups data series with 4 different length
本文从信息论中shannon熵定理出发，对无损压缩技术进行系统地分析，用c语言实现了其中的算术编码算法，并用它对35组、四种不同长度数据序列进行了压缩，给出了实验结果，然后从压缩比、压缩比随字符串长度的变换趋势、算法稳定性和算法复杂性等四个方面对其与其它三种压缩算法lzw 、 lz77 、 rle进行了分析与比较。

Arithmetic coding is a form of entropy encoding used in lossless data compression. Normally, a string of characters such as the words "hello there" is represented using a fixed number of bits per character, as in the ASCII code.
