On cyclic reversible self-dual additive codes with odd length over Z/sub 2//sup 2/

Abstract

Several additive codes of odd length over Z/sub 2//sup 2/ are introduced. These codes are cyclic and reversible. Furthermore, they are self-dual under an appropriately selected binary-valued inner product. Some binary derivatives of these codes have good parameters. All cyclic and reversible [5,2.5,3] additive codes over Z/sub 2//sup 2/ are isomorphic and possess interesting properties.
