| 摘 要： | 算术码是一种有效的信息保持型信源编码技术。基于Ｒｉｓａｎｅｎ和Ｍｏｈｉｕｄｄｉｎ提出的算法（ＲＭ法），给出了一种仅采用移位加法和查表处理的二值免乘法算术码方案。理论分析和软件模拟表明该方案具有较好的性能。

| Abstract: | Arithmetic coding is a powerful lossless data compression technique.Based on the scheme proposed by Rissanen and Mohiaddin,this paper gives a black_white alphabet multiplication free arithmetic coding scheme which only uses shift and add and looks up table.Both theoretical analysis and computer simulation show that the multiplication free scheme is better for all cases. |
