On structure and distances of some classes of repeated-root constacyclic codes over Galois rings
© 2016 Elsevier Inc. The structure of λ-constacyclic codes of length 2 s over the Galois ring GR(2 a ,m) is obtained, for any unit λ of the form 4z−1, z∈GR(2 a ,m). The duals codes and necessary and sufficient conditions for the existence of a self-dual λ-constacyclic code are provided. Among others...
