【摘要】 6∶8平衡调制码是体全息存储中一种有效的通道编码方法.给出了6∶8平衡调制编码的一种编码译码方案,同时介绍了排序法,完全相关法以及V iterbi算法3种码字检测方法,并指出了V iterbi检测法如何用13次加法操作和13次比较完成码字检测.最后,对几种码字检测方法作了对比,指出对于软件实现,优选排序法.更多还原

【Abstract】 6∶8 balanced modulation code is an efficient channel coding for Holographic Data Storage.In this paper,a scheme of 6∶8 balanced modulation coding and decoding is given,and three codeword detection methods including sording,complete correlation and Viterbi Algorithm are presented.This paper also points out how to complete codeword detection using only 13 add operations and 13 compares.At last,sorting method is recommended for software implementation by comparing three detection method.更多还原
