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

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

The ${\mathbb{Z}}_{p^s}$-additive codes of length $n$ are subgroups of ${\mathbb{Z}}_{p^s}^n$, and can be seen as a generalization of linear codes over ${\mathbb{Z}}_2$, ${\mathbb{Z}}_4$, or ${\mathbb{Z}}_{2^s}$ in general. A $\Z_…
