MRD代码的标识符

Identifiers for MRD-codes

Luca Giuzzi, Ferdinando Zullo

摘要:

对于参数$n$和$k$的任何容许值,存在$[n,k]$ -最大秩距离${\mathbb F}_q$ -线性码。事实上,可以证明,如果考虑足够大的域扩张,几乎所有的秩距离码都是MRD。另一方面,目前已知的此类代码的等效家庭很少。本文研究了MRD码的一些不变量,并对已知的MRD码族给出了它们的值,给出了广义扭Gabidulin码的一个新的刻画。

英文摘要:

For any admissible value of the parameters $n$ and $k$ there exist $[n,k]$-Maximum Rank distance ${\mathbb F}_q$-linear codes. Indeed, it can be shown that if field extensions large enough are considered, almost all rank distance codes are MRD. On the other hand, very few families up to equivalence of such codes are currently known. In the present paper we study some invariants of MRD codes and evaluate their value for the known families, providing a new characterization of generalized twisted Gabidulin codes.
