随着科学技术的发展,信息、通信类本科生学习信息论是十分必要的。算术编码是基于统计的、无损数据压缩效率最高的编码方法。针对算术编码教学中存在的问题,本文进一步探讨了算术编码的编码、译码过程,提出了编码过程中需要注意的问题,并将算术编码与哈夫曼编码做了比较。最后,用Matlab实现了算术编码的具体实例。

With the development of science and technology,it is necessary for the students of specialty on information science and communication technique to learn the course of Information Theory and Coding Theory.Arithmetic coding is the most powerful technique for lossless data compression.For problems in arithmetic teaching,the paper shows the process of arithmetic coding and decoding,illustrating with specific examples.The problems which needs attention in coding are proposed,and compared with the Huffman coding.Finally,we achieved specific examples of arithmetic coding with Matlab.
