On additive MDS codes over small fields

چکیده
Let $ C be a (n,q^{2k},n-k+1)_{q^2} additive MDS code which is linear over {\mathbb F}_q $. We prove that if n \geq q+k and k+1 of the projections are F}_{q^2} then use this geometrical theorem, other geometric arguments some computations to classify all codes for q \in \{4,8,9\} also longest F}_{16} F}_4 In these cases, classifications not only verify conjecture codes, but confirm there no non-linear perform as well their counterparts. These results imply quantum holds \{ 2,3\}

New MDS Self-Dual Codes over Large Finite Fields
We construct MDS Euclidean and Hermitian self-dual codes over large finite fields of odd and even characteristics. Our codes arise from cyclic and negacyclic duadic codes. ∗Faculty of Mathematics USTHB, University of Sciences and Technology of Algiers, B.P 32 El Alia, Bab Ezzouar, Algiers, Algeria
متن کاملNew MDS or near MDS self-dual codes over finite fields
The study of MDS self-dual codes has attracted lots of attention in recent years. There are many papers on determining existence of q−ary MDS self-dual codes for various lengths. There are not existence of q−ary MDS self-dual codes of some lengths, even these lengths < q. We generalize MDS Euclidean self-dual codes to near MDS Euclidean self-dual codes and near MDS isodual codes. And we obtain ...
متن کاملMDS matrices over small fields: A proof of the GM-MDS conjecture
The GM-MDS conjecture of Dau et al. (ISIT 2014) speculates that the MDS condition, which guarantees the existence of MDS matrices with a prescribed set of zeros over large fields, is in fact sufficient for existence of such matrices over small fields. We prove this conjecture.
متن کاملMDS codes over finite principal ideal rings
The purpose of this paper is to study codes over finite principal ideal rings. To do this, we begin with codes over finite chain rings as a natural generalization of codes over Galois rings GR(pe, l) (including Zpe). We give sufficient conditions on the existence of MDS codes over finite chain rings and on the existence of self-dual codes over finite chain rings. We also construct MDS self-dual...
متن کاملMDS and self-dual codes over rings
In this paper we give the structure of constacyclic codes over formal power series and chain rings. We also present necessary and sufficient conditions on the existence of MDS codes over principal ideal rings. These results allow for the construction of infinite families of MDS self-dual codes over finite chain rings, formal power series and principal ideal rings.
