Daniella Bar-Lev, Sagi Marcovich, Eitan Yaakobi, Yonatan Yehezkeally

AI总结:

本文研究对抗性撕纸信道,将DNA存储中片段乱序问题从概率模型推广到最坏情况,构造了可实现渐近最优速率且支持高效编解码的编码方案,并扩展到多链存储、替换错误和不完全覆盖等场景。

摘要:

我们研究对抗性撕纸信道。该问题源于DNA数据存储应用,其中携带信息的DNA链可能断裂成较小的片段,并以乱序方式被接收。我们的模型将先前研究的概率性设定扩展到最坏情况。我们针对信道中可实现非零渐近速率的任意参数开发了编码构造,并证明我们的构造在允许高效编码与解码的同时,实现了渐近最优速率。最后,我们将结果扩展到相关设定,包括多链存储、替换错误的存在或不完全覆盖。

英文摘要:

We study the adversarial torn-paper channel. This problem is motivated by applications in DNA data storage where the DNA strands that carry information may break into smaller pieces which are received out of order. Our model extends the previously researched probabilistic setting to the worst-case. We develop code constructions for any parameters of the channel for which non-vanishing asymptotic rate is possible and show our constructions achieve asymptotically optimal rate while allowing for efficient encoding and decoding. Finally, we extend our results to related settings included multi-strand storage, presence of substitution errors, or incomplete coverage.
