摘　　要：Ａｄｌｅｒ等人算法能保证滑动窗译码，但对状态的归并重视不够。本文在Ａｄｌｅｒ等人算法的基础上，充分考虑了状态归并，提出了改进Ａｄｌｅｒ等人算法的方法。与Ａｄｌｅｒ等人的算法相比，改进后的算法能使设计的ＲＬＬ码使用更少的编码状态。The Adler and et al.'s algorithm can guarantee the sliding block decodable,however state merging is less considered.In this paper,state merging is fully considered based on the Adler and et al.'s algorithm.The method about how to improve the Adler and et al.'s algorithm is presented.The improved algorithm may usually result in less states for encoding a RLL code than Adler and et al.'s Algorithm.
