New optimal linear codes over $\ZZ_4$
Hopein Christofen Tang, Djoko Suprijanto
In this work, we present novel approaches for constructing linear codes over $\ZZ_4$ from the known ones. We succeeded in obtaining new linear codes, many of which are optimal. In…
Self-dual double cyclic codes over
Ricky Aditya, Aleams Barra, Djoko Suprijanto
The paper studies self‑dual double cyclic codes over finite fields, giving conditions for their existence and construction methods for various code lengths.
A general family of Plotkin-optimal two-weight codes over
Hopein Christofen Tang, Djoko Suprijanto
We obtain all possible parameters of Plotkin-optimal two-Lee weight projective codes over together with their weight distributions. We show the existence of codes w…
Skew cyclic codes over with derivation: structural properties and computational results
Djoko Suprijanto, Hopein Christofen Tang
In this work, we study a class of skew cyclic codes over the ring where with an automorphism and a derivation namely codes a…
