Weight distributions of simplex codes over finite chain rings and their Gray map images

Cristina Fernández-Córdoba, Sergi Sánchez-Aragón, Mercè Villanueva

A linear code of length $n$ over a finite chain ring $R$ with residue field $\F_q$ is a $R$ -submodule of $R^{n}$ . A $R$ -linear code is a code over $\F_q$ (not necessarily linear) whi…

$Z_{2} Z_{4} Z_{8}$ -Additive Hadamard Codes

Dipak K. Bhunia, Cristina Fernández-Córdoba, Mercè Villanueva

The $Z_{2} Z_{4} Z_{8}$ -additive codes are subgroups of $Z_{2}^{α_{1}} \times Z_{4}^{α_{2}} \times Z_{8}^{α_{3}}$ , and can be seen as linear codes…

Construction and Linearity of Z_pZ_{p^2}-Linear Generalized Hadamard Codes

Dipak K. Bhunia, Cristina Fernández-Córdoba, Mercè Villanueva

The $Z_{p} Z_{p^{2}}$ -additive codes are subgroups of $Z_{p}^{α_{1}} \times Z_{p^{2}}^{α_{2}}$ , and can be seen as linear codes over $Z_{p}$ when $α_{2} = 0$ , $Z_{p^{2}}$ -additive codes when $α_1…

Equivalences among Z_{p^s}-linear Generalized Hadamard Codes

Dipak K. Bhunia, Cristina Fernández-Córdoba, Carlos Vela +1

The $Z_{p^{s}}$ -additive codes of length $n$ are subgroups of $Z_{p^{s}}^{n}$ , and can be seen as a generalization of linear codes over $Z_{2}$ , $Z_{4}$ , or $Z_{2^{s}}$ in general. A $\Z_…

Rank and Kernel of $F_{p}$ -Additive Generalised Hadamard Codes

Steven T. Dougherty, Josep Rifà, Mercè Villanueva

A subset of a vector space $F_{q}^{n}$ is $K$ -additive if it is a linear space over the subfield $K \subseteq F_{q}$ . Let $q = p^{e}$ , $p$ prime, and $e > 1$ . Bounds on the ra…

On the Kernel of $Z_{2^{s}}$ -Linear Simplex and MacDonald Codes

Cristina Fernández-Córdoba, Carlos Vela, Mercè Villanueva

The $Z_{2^{s}}$ -additive codes are subgroups of $Z_{2^{s}}^{n}$ , and can be seen as a generalization of linear codes over $Z_{2}$ and $Z_{4}$ . A $Z_{2^{s}}$ -linear code is a binary code w…
