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…

A multiset approach to MacWilliams identities
Hopein Christofen Tang
We interpret the symmetrized weight enumerator of linear codes over finite commutative Frobenius rings as a summation over multisets and thereby provide a new proof of the MacWilli…
