Quasi-twisted codes as contractions of quasi-cyclic codes
Özkaya, Buket; Özbudak, Ferruh (2023-10-01)
A Comparison of Distance Bounds for Quasi-Twisted Codes
Ezerman, Martianus Frederic; Lampos, John Mark; Ling, San; Özkaya, Buket; Tharnnukhroh, Jareena (2021-10-01)
Spectral bounds on the minimum distance of quasi-twisted codes over finite fields are proposed, based on eigenvalues of polynomial matrices and the corresponding eigenspaces. They generalize the Semenov-Trifonov and Zeh-Li...
Quasi-cyclic codes
Özkaya, Buket; Güneri, Cem; Ling, San (CRC, New York , 2021-03-01)
New bounds on the minimum distance of cyclic codes
Ling, San; Özkaya, Buket (2021-02-01)
Two bounds on the minimum distance of cyclic codes are proposed. The first one generalizes the Roos bound by embedding the given cyclic code into a cyclic product code. The second bound also uses a second cyclic code, name...
On complementary dual multinegacirculant codes
Alahmadi, Adel; Guneri, Cem; Özkaya, Buket; Shoaib, Hatoon; Sole, Patrick (2020-01-01)
Linear codes with complementary duals intersect with their duals trivially. Multinegacirculant codes that are complementary dual are characterized algebraically and some good codes are found in this family. Exact enumerati...
Multidimensional quasi-twisted codes: equivalent characterizations and their relation to multidimensional convolutional codes
Ling, San; Özkaya, Buket (2019-12-01)
We study multidimensional analogues of quasi-twisted codes from different points of view. Their concatenated structure allows us to characterize self-dual and complementary-dual classes of such codes as well as to show tha...
Good Stabilizer Codes from Quasi-Cyclic Codes over F-4 and F-9
Ezerman, Martianus Frederic; Ling, San; Özkaya, Buket; Sole, Patrick (2019-01-01)
We apply quantum Construction X on quasi-cyclic codes with large Hermitian hulls over F-4 and F-9 to derive good qubit and qutrit stabilizer codes, respectively. In several occasions we obtain quantum codes with stricly im...
Spectral Bounds for Quasi-Twisted Codes
Ezerman, Martianus Frederic; Ling, San; Özkaya, Buket; Tharnnukhroh, Jareena (2019-01-01)
New lower bounds on the minimum distance of quasi-twisted codes over finite fields are proposed. They are based on spectral analysis and eigenvalues of polynomial matrices. They generalize the Semenov-Trifonov and Zeh-Ling...
On Linear Complementary Pair of nD Cyclic Codes
Guneri, Cem; Özkaya, Buket; Sayici, Selcen (2018-12-01)
The security parameter for a linear complementary pair (C, D) of codes is defined to be the minimum of the minimum distances d(C) and d(D-perpendicular to). Recently, Carlet et al. showed that if C and D are both cyclic or...
On self-dual double negacirculant codes
Alahmadi, Adel; Guneri, Cern; Özkaya, Buket; Shoaib, Hatoon; Sole, Patrick (2017-05-01)
Double negacirculant (DN) codes are the analogues in odd characteristic of double circulant codes. Self-dual DN codes are shown to have a transitive automorphism group. Exact counting formulae are derived for DN codes. The...
