Optimal Self-Dual Codes Over With Respect to the Hamming Weight
Koichi Betsumiya · 2004
In this correspondence, we study optimal self-dual codes and Type IVself-dual codes over the ring of order . We give im- proved upper bounds on minimum Hamming and Lee weights for such codes. Using the bounds, we determine the highest minimum Hamming and Lee weights for such codes of lengths up to . We also construct optimal self-dual codes and Type IVself-dual codes.
