Generalized weights: an anticode approach
Alberto Ravagnani
In this paper we study generalized weights as an algebraic invariant of a code. We first describe anticodes in the Hamming and in the rank metric, proving in particular that optima…
Rank-metric codes and their duality theory
Alberto Ravagnani
We compare the two duality theories of rank-metric codes proposed by Delsarte and Gabidulin, proving that the former generalizes the latter. We also give an elementary proof of Mac…
Subspace codes from Ferrers diagrams
Elisa Gorla, Alberto Ravagnani
In this paper we give new constructions of Ferrer diagram rank metric codes, which achieve the largest possible dimension. In particular, we prove several cases of a conjecture by…
Optimal Ferrers Diagram Rank-Metric Codes
Antonia Wachter-Zeh, Tuvi Etzion
Optimal rank-metric codes in Ferrers diagrams are considered. Such codes consist of matrices having zeros at certain fixed positions and can be used to construct good codes in the…
