纠正限制性错误的代码

Codes correcting restricted errors

Igor E. Shparlinski, Arne Winterhof

摘要:

本文研究了$(B-1)$维线性码的最大可能长度$B$,它能纠正来自受限集$\mathcal{A}\subseteq \mathbb{F}_q^*$的最多达$t$的错误.这样的代码可以应用于多级闪存。此外,在$q=p$是一个素数的情况下,错误是有限的一个常数,我们表明,往往是原始的$\ell$ th根的单位,其中$\ell$是一个素因子的$p-1$,定义良好的这样的代码。

英文摘要:

We study the largest possible length $B$ of $(B-1)$-dimensional linear codes over $\mathbb{F}_q$ which can correct up to $t$ errors taken from a restricted set $\mathcal{A}\subseteq \mathbb{F}_q^*$. Such codes can be applied to multilevel flash memories. Moreover, in the case that $q=p$ is a prime and the errors are limited by a constant we show that often the primitive $\ell$th roots of unity, where $\ell$ is a prime divisor of $p-1$, define good such codes.
