Permutation codes over finite fields

Irwansyah, Intan Muchtadi-Alamsyah, Aleams Barra

In this paper we describe a class of codes called {\it permutation codes}. This class of codes is a generalization of cyclic codes and quasi-cyclic codes. We also give some example…

Codes over an algebra over ring

Irwansyah, Djoko Suprijanto

In this paper, we consider some structures of linear codes over the ring $R_{k} = R [v_{1}, \dots, v_{k}],$ where $v_{i}^{2} = v_{i}$ forall $i = 1, \dots, k),$ and $R$ is a finite commutative…

Structure of linear codes over the ring $B_{k}$

Irwansyah, Djoko Suprijanto

We study the structure of linear codes over the ring $B_{k}$ which is defined by $F_{p^{r}} [v_{1}, v_{2}, \dots, v_{k}] / ⟨ v_{i}^{2} = v_{i}, v_{i} v_{j} = v_{j} v_{i} ⟩_{i, j = 1}^{k} .$ In order t…

$Θ_{S} -$ cyclic codes over $A_{k}$

Irwansyah, Aleams Barra, Steven T. Dougherty +5

We study $Θ_{S} -$ cyclic codes over the family of rings $A_{k} .$ We characterize $Θ_{S} -$ cyclic codes in terms of their binary images. A family of Hermitian inner-products is defined and…

A Note on The Enumeration of Euclidean Self-Dual Skew-Cyclic Codes over Finite Fields

Irwansyah, Intan Muchtadi-Alamsyah, Ahmad Muchlis +2

In this paper we give the enumeration formulas for Euclidean self-dual skew-cyclic codes over finite fields when $(n, ∣ θ ∣) = 1$ and for some cases when $(n, ∣ θ ∣) > 1,$ where $n$ is the l…
