Structure and performance of generalized quasi-cyclic codes [PDF]

open access: yesFinite Fields and Their Applications, 2017
Generalized quasi-cyclic (GQC) codes form a natural generalization of quasi-cyclic (QC) codes. They are viewed here as mixed alphabet codes over a family of ring alphabets.

On the additive cyclic structure of quasi-cyclic codes [PDF]

open access: yesDiscrete Mathematics, 2018
An index l , length m l quasi-cyclic code can be viewed as a cyclic code of length m over the field F q l via a basis of the extension F q l ∕ F q . However, this cyclic code is only linear over F q , making it an additive cyclic code, or an F q -linear ...

Enumeration formulae for self-dual, self-orthogonal and complementary-dual quasi-cyclic codes over finite fields

open access: yesFinite Fields and Their Applications, 2018
A linear code with a complementary dual (an LCD code) is a linear code \(C\) whose dual \(C^ \perp\) satisfies \(C\cap C^ \perp= \{0\}\). Necessary and sufficient conditions for a cyclic code be an LCD code were given by \textit{X. Yang} and \textit{J. L. Massey} [Discrete Math. 126, No. 1--3, 391--393 (1994; Zbl 0790.94022)].

Efficient One-Time Signatures from Quasi-Cyclic Codes: A Full Treatment

open access: yesCryptography, 2018
The design of a practical code-based signature scheme is an open problem in post-quantum cryptography. This paper is the full version of a work appeared at SIN’18 as a short paper, which introduced a simple and efficient one-time secure signature ...

A SPECIAL CLASS OF QUASI-CYCLIC CODES

open access: yesBulletin of the Australian Mathematical Society, 2017
We study a special class of quasi-cyclic codes, obtained from a cyclic code over an extension field of the alphabet field by taking its image on a basis. When the basis is equal to its dual, the dual code admits the same construction.

On the hull and complementarity of one generator quasi-cyclic codes and four-circulant codes [PDF]

open access: yesJournal of Algebra and its Applications, 2023
We study one generator quasi-cyclic codes and four-circulant codes, which are also quasi-cyclic but have two generators. We state the hull dimensions for both classes of codes in terms of the polynomials in their generating elements.

On construction of quantum codes with dual-containing quasi-cyclic codes [PDF]

open access: yesQuantum Information Processing, 2022
One of the main objectives of quantum error-correction theory is to construct quantum codes with optimal parameters and properties. In this paper, we propose a class of 2-generator quasi-cyclic codes and study their applications in the construction of ...

Self-dual 2-quasi-cyclic Codes and Dihedral Codes [PDF]

open access: yesFinite Fields Their Appl., 2022
We characterize the structure of 2-quasi-cyclic codes over a finite field F by the so-called Goursat Lemma. With the characterization, we exhibit a necessary and sufficient condition for a 2-quasi-cyclic code being a dihedral code.
