In this work, we focus on constructing binary self-dual [68, 34, 12] and [88, 44, 14] codes with
new parameters in their weight enumerators. For this purpose, we present a new bordered …

In this work, we apply the idea of composite matrices arising from group rings to derive a
number of different techniques for constructing self-dual codes over finite commutative …

In this work, we present a new method for constructing self-dual codes over finite
commutative rings R with characteristic 2. Our method involves searching for k× 2 k matrices …

In this work, we define a modification of a bordered construction for self-dual codes which
utilises $\lambda $-circulant matrices. We provide the necessary conditions for the …

In this work, we give three new techniques for constructing Hermitian self-dual codes over
commutative Frobenius rings with a non-trivial involutory automorphism using λ-circulant …

In this work, we give a new technique for constructing self-dual codes over commutative
Frobenius rings using λ-circulant matrices. The new construction was derived as a …

The main research presented in this thesis is around constructing binary self-dual codes
using group rings together with some well-known code construction methods and the study …

The initial research presented in this thesis is the structure of the unit group of the group ring
Cn x D6 over a field of characteristic 3 in terms of cyclic groups, specifically U (F3t (Cn x …
