Hamming Distance of Constacyclic Codes of Length ps Over Fpm+uFpm+u²Fpm

open access: yesIEEE Access, 2021
Let $p$ be any prime, $s$ and $m$ be positive integers. In this paper, we completely determine the Hamming distance of all constacyclic codes of length $p^s$ over the finite commutative chain ring $\mathbb {F}_{p^m}+ u\mathbb {F}_{p^m} + u^{2 ...

Self-Dual Codes, Symmetric Matrices, and Eigenvectors

open access: yesIEEE Access, 2021
We introduce a consistent and efficient method to construct self-dual codes over $GF(q)$ using symmetric matrices and eigenvectors from a self-dual code over $GF(q)$ of smaller length where $q \equiv 1 \pmod 4$ . Using this method, which is called a

Some Results on Self-Complementary Linear Codes

open access: yesMathematics, 2023
Binary codes have a special place in coding theory since they are one of the most commonly used in practice. There are classes of codes specific only to the binary case. One such class is self-complementary codes.

Binary code optimization

open access: yesCoRR, 2021
This article shows that any type of binary data can be defined as a collection from codewords of variable length. This feature helps us to define an Injective and surjective function from the suggested codewords to the required codewords. Therefore, by replacing the new codewords, the binary data becomes another binary data regarding the intended goals.

Repeated-Root Constacyclic Codes Over the Chain Ring Fpm[u]/⟨u3

open access: yesIEEE Access, 2020
Let Z = Fpm[u]/(u3) be the finite commutative chain ring, where p is a prime, m is a positive integer and Fpm is the finite field with pm elements. In this paper, we determine all repeated-root constacyclic codes of arbitrary lengths over Z and their ...

Asymptotically Optimal Codes Correcting Fixed-Length Duplication Errors in DNA Storage Systems [PDF]

open access: yesIEEE Communications Letters, 2018
A (tandem) duplication of length ${k} $ is an insertion of an exact copy of a substring of length ${k} $ next to its original position.

New Constructions of Optimal Locally Repairable Codes With Super-Linear Length [PDF]

open access: yesIEEE Transactions on Information Theory, 2020
As an important coding scheme in modern distributed storage systems, locally repairable codes (LRCs) have attracted a lot of attentions from perspectives of both practical applications and theoretical research.

On Optimal Locally Repairable Codes and Generalized Sector-Disk Codes [PDF]

open access: yesInternational Symposium on Information Theory, 2020
Optimal locally repairable codes with information locality are considered. Optimal codes are constructed, whose length is also order-optimal with respect to a new bound on the code length derived in this paper.

Optimal Narain CFTs from codes

open access: yesJournal of High Energy Physics, 2022
Recently established connection between additive codes and Narain CFTs provides a new tool to construct theories with special properties and solve modular bootstrap constraints by reducing them to algebraic identities.

BVPs Codes for Solving Optimal Control Problems

open access: yesMathematics, 2021
Optimal control problems arise in many applications and need suitable numerical methods to obtain a solution. The indirect methods are an interesting class of methods based on the Pontryagin’s minimum principle that generates Hamiltonian Boundary Value ...
