Abstract
In this correspondence, we study optimal self-dual codes and Type IV self-dual codes over the ring double struct F sign2 × double struct F sign2 of order 4. We give improved 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 30. We also construct optimal self-dual codes and Type IV self-dual codes.
