Abstract :
A new transform is denned for the class of cocyclic group ring codes over a Galois ring, where the underlying group is Abelian and the cocycle is the Vandermonde-cocycle on the Abelian group. The class of Vandermonde-cocyclic (VC) group ring codes are characterized using this new transform by means of a structure theorem for VC group rings.
