Self-Dual Codes over Z_2xZ_4
J. Borges, S. T. Dougherty, C. Fernandez-Cordoba
Self-dual codes over are subgroups of that are equal to their orthogonal under an inner-product that relates to the binary Hamming scheme. Thr…
Propelinear structure of Z_{2k}-linear codes
J. Borges, C. Fernandez-Cordoba, J. Rifa
Let C be an additive subgroup of for any . We define a Gray map such that $Φ(\codi)$ is a binary propelinear code and,…
On the minimum distance graph of an extended Preparata code
C. Fernández-Córdoba, K. T. Phelps
The minimum distance graph of an extended Preparata code P(m) has vertices corresponding to codewords and edges corresponding to pairs of codewords that are distance 6 apart. The c…
Z2Z4-linear codes: rank and kernel
Cristina Fernandez-Cordoba, Jaume Pujol, Merce Villanueva
A code C is Z2Z4-additive if the set of coordinates can be partitioned into two subsets X and Y such that the punctured code of C by deleting the coordinates outside X (respectivel…
Z2Z4-linear codes: generator matrices and duality
J. Borges, C. Fernandez, J. Pujol +2
A code is -additive if the set of coordinates can be partitioned into two subsets and such that the punctured code of by deleting the coordi…
