Two-Weight Codes Punctured from Irreducible Cyclic Codes

Abstract

In this paper, a class of two-weight linear codes over F(q) is presented. This family of codes is punctured from irreducible cyclic codes and contains a subclass of MDS codes and other optimal codes. Their dual codes are also optimal in some cases. The punctured codes are in general better than the original irreducible cyclic codes in terms of information rate and error correcting capability.
