A circulant approach to skew-constacyclic codes [PDF]

open access: yesFinite Fields and Their Applications, 2015
We introduce circulant matrices that capture the structure of a skew-polynomial ring F[x;θ] modulo the left ideal generated by a polynomial of the type x^n-a. This allows us to develop an approach to skew-constacyclic codes based on such circulants.

Constacyclic codes over finite fields [PDF]

open access: yesFinite Fields and Their Applications, 2012
An equivalence relation called isometry is introduced to classify constacyclic codes over a finite field; the polynomial generators of constacyclic codes of length $\ell^tp^s$ are characterized, where $p$ is the characteristic of the finite field and $\ell$ is a prime different from $p$.

Several families of irreducible constacyclic and cyclic codes

open access: yesDesigns, Codes and Cryptography, 2023
In this paper, several families of irreducible constacyclic codes over finite fields and their duals are studied. The weight distributions of these irreducible constacyclic codes and the parameters of their duals are settled. Several families of irreducible constacyclic codes with a few weights and several families of optimal constacyclic codes are ...

A class of constacyclic codes over Zpm [PDF]

open access: yesFinite Fields and Their Applications, 2010
AbstractWe study (1+λp)-constacyclic codes over Zpm of an arbitrary length, where λ is a unit of Zpm and m⩾2 is a positive integer. We first derive the structure of (1+λp)-constacyclic codes of length ps over GR(pm,a) and determine the Hamming and homogeneous distances of such constacyclic codes.

Quantum Codes as an Application of Constacyclic Codes

open access: yesAxioms
The main focus of this paper is to analyze the algebraic structure of constacyclic codes over the ring R=Fp+w1Fp+w2Fp+w22Fp+w1w2Fp+w1w22Fp, where w12−α2=0, w1w2=w2w1, w23−β2w2=0, and α,β∈Fp∖{0}, for a prime p. We begin by introducing a Gray map defined over R, which is associated with an invertible matrix.

A new family of EAQMDS codes constructed from constacyclic codes

open access: yes, 2021
In this paper, a family of new entanglement-assisted quantum error-correcting codes (EAQECCs) is constructed from constacyclic codes with length n=q2+1a by giving a new method to select defining sets, where a= m2+ 1 , m> 2 is even and q is an odd prime ...

Linear complementary pairs of skew constacyclic codes [PDF]

open access: yes, 2023
Linear complementary pairs (LCPs) of codes have been studied since they were introduced in the context of discussing mitigation measures against possible hardware attacks to integrated circuits. Since the security parameters for LCPs of codes are defined

Two Classes of Constacyclic Codes with Variable Parameters

open access: yes, 2023
Constacyclic codes over finite fields are a family of linear codes and contain cyclic codes as a subclass. Constacyclic codes are closely related to many areas of mathematics and outperform cyclic codes in several aspects.
