New Criteria for MRD and Gabidulin Codes and some Rank-Metric Code Constructions (1507.08641v3)
Published 30 Jul 2015 in cs.IT and math.IT
Abstract: In this work we present a new criterion to check if a given rank-metric code is a maximum rank distance (MRD) code. Moreover, we derive a criterion to check if a given MRD code is a generalized Gabidulin code. We then use these results to come up with constructions of linear MRD codes of dimension 2 that are not generalized Gabidulin codes.
