两个插入畸变序列的重构

Reconstruction of Sequences Distorted by Two Insertions

Zuo Ye, Xin Liu, Xiande Zhang, Gennian Ge

摘要:

重建码是纠错码的推广,其可以通过给定数量的噪声读取来纠正错误。Levenshtein于2001年开始研究这种代码,最近由于在现代存储设备中的应用而发展,例如赛道存储器和DNA存储。关于这个主题的中心问题是设计具有对于给定数目的噪声读段$N$尽可能小的冗余度的代码。在本文中,这样的代码的最小冗余的二进制信道正好有两个插入渐近确定的所有值的$N\ge 5$。以前,这样的代码只研究了单一的编辑错误或两个删除错误的通道。

英文摘要:

Reconstruction codes are generalizations of error-correcting codes that can correct errors by a given number of noisy reads. The study of such codes was initiated by Levenshtein in 2001 and developed recently due to applications in modern storage devices such as racetrack memories and DNA storage. The central problem on this topic is to design codes with redundancy as small as possible for a given number $N$ of noisy reads. In this paper, the minimum redundancy of such codes for binary channels with exactly two insertions is determined asymptotically for all values of $N\ge 5$. Previously, such codes were studied only for channels with single edit errors or two-deletion errors.
