$b$ -符号读取通道的最大距离可分离码

Maximum Distance Separable Codes for $b$-Symbol Read Channels

Baokun Ding, Tao Zhang, Gennian Ge

摘要:

最近,Yaakobi等人引入了用于$b$ -符号读取通道的代码,其中读取操作作为$b>2$符号的连续序列来执行。本文建立了$b$ -符号码的Singleton型界。满足Singleton型界的码被称为最大距离可分离(MDS)码,并且在它们达到最大最小$b$ -距离的意义上它们是最优的。基于射影几何和常循环码,构造了有限域上的线性MDS $b$ -符号码.在某种意义上,我们完全确定了有限域上线性MDS $b$ -符号码的存在性。

英文摘要:

Recently, Yaakobi et al. introduced codes for $b$-symbol read channels, where the read operation is performed as a consecutive sequence of $b>2$ symbols. In this paper, we establish a Singleton-type bound on $b$-symbol codes. Codes meeting the Singleton-type bound are called maximum distance separable (MDS) codes, and they are optimal in the sense they attain the maximal minimum $b$-distance. Based on projective geometry and constacyclic codes, we construct new families of linear MDS $b$-symbol codes over finite fields. And in some sense, we completely determine the existence of linear MDS $b$-symbol codes over finite fields for certain parameters.
