Self-Dual and Complementary Dual Abelian Codes over Galois Rings [PDF]

open access: yes, 2019
Self-dual and complementary dual cyclic/abelian codes over finite fields form important classes of linear codes that have been extensively studied due to their rich algebraic structures and wide applications.

Quality of cause-of-death data in Brazil: Garbage codes among registered deaths in 2000 and 2015 [PDF]

open access: yesRevista Brasileira de Epidemiologia, 2019
Introduction: reliability of mortality data is essential for health assessment and planning. In Brazil, a high proportion of deaths is attributed to causes that should not be considered as underlying causes of deaths, named garbage codes (GC).

On cyclic DNA codes over the rings Z4 + wZ4 and Z4 + wZ4 + vZ4 + wvZ4

open access: yesBiomath, 2017
The structures of cyclic DNA codes of odd length over the finite rings R = Z4 + wZ4, w^2 = 2 and S = Z4 + wZ4 + vZ4 + wvZ4; w^2 = 2; v^2 =v; wv = vw are studied.

More Constructions of 3-Weight Linear Codes

open access: yesJournal of Mathematics, 2021
Linear codes with few weights have become an interesting research topic and important applications of cryptography and coding theory. In this paper, we apply some ternary near-bent and 2-plateaued functions or r-ary functions to construct more 3-weight ...

MDS Symbol-Pair Repeated-Root Constacylic Codes of Prime Power Lengths Over $\mathbb F_{p^m}+ u \mathbb F_{p^m}$

open access: yesIEEE Access, 2019
MDS codes have the highest possible error-detecting and error-correcting capability among codes of given length and size. Let p be any prime, and s, m be positive integers.

Linear Codes Arise From New Complete (n,r)-arcs in PG(2,29) [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2009
This paper presents the recently-discovered linear [n,3,d] codes over PG(2,29) that arises from a complete (n,r)-arcs which the paper[12] presented it for the first time.

On the non-minimality of the largest weight codewords in the binary Reed-Muller codes [PDF]

open access: yes, 2011
The study of minimal codewords in linear codes was motivated by Massey who described how minimal codewords of a linear code define access structures for secret sharing schemes.

Systematic Codes for Rank Modulation [PDF]

open access: yes, 2014
The goal of this paper is to construct systematic error-correcting codes for permutations and multi-permutations in the Kendall's $\tau$-metric. These codes are important in new applications such as rank modulation for flash memories. The construction is

DNA Code from Cyclic and Skew Cyclic Codes over F4[v]/v3

open access: yesEntropy, 2023
The main motivation of this work is to study and obtain some reversible and DNA codes of length n with better parameters. Here, we first investigate the structure of cyclic and skew cyclic codes over the chain ring R:=F4[v]/⟨v3⟩.
