On MDS codes via Cauchy matrices
Authors:Roth   R.M. Lempel   A.
Affiliation:Dept. of Comput. Sci., Technion, Haifa;
Abstract:A special form of Cauchy matrix is used to obtain a tighter bound for the validity region of the maximum distance separable (MDS) conjecture and a new compact characterization of generalized Reed-Solomon codes. The latter is further used to obtain constructions and some existence results for long [2k, k] double-circulant MDS codes
