Construction of MDS Euclidean Self-Dual Codes via Two Subsets [PDF]

open access: yesIEEE Transactions on Information Theory, 2020
The parameters of a $q$ -ary MDS Euclidean self-dual codes are completely determined by its length and the construction of MDS Euclidean self-dual codes with new length has been widely investigated in recent years.

Binary formally self-dual odd codes [PDF]

open access: yes, 2017
Most of the research on formally self-dual (f.s.d.) codes has been developed for binary f.s.d. even codes, but only limited research has been done for binary f.s.d. odd codes. In this article we complete the classification of binary f.s.d.

Classification of self-dual cyclic codes over the chain ring Z(p)[u]/< u(3)> [PDF]

open access: yes, 2021
We classify all the cyclic self-dual codes of length p(k) over the finite chain ring R := Z(p)[u]/< u(3)>, which is not a Galois ring, where p is a prime number and k is a positive integer.

Extended binary Golay codes by a group algebra of one group

open access: yesНауковий вісник Ужгородського університету. Серія: Математика і інформатика, 2020
Extended binary Golay codes are examples of extreme binary self-dual codes of Type II (linear binary self-dual codes with Hamming distance between arbitrary codewords which are multiples of 4 that has the highest possible minimum Hamming distance among ...

Narain CFTs and error-correcting codes on finite fields

open access: yesJournal of High Energy Physics, 2022
We construct Narain CFTs from self-dual codes on the finite field F p through even self-dual lattices for any prime p > 2. Using this correspondence, we can relate the spectral gap and the partition function of the CFT to the error correction capability ...

Reversible Self-Dual Codes Over the Ring F2 + uF2

open access: yesIEEE Access
In this study, we introduce bisymmetric self-dual codes over the finite field ${\mathbb F}_{2}$ of order two. We developed a method to generate binary bisymmetric self-dual codes from a small-length bisymmetric self-dual code by increasing its length ...

Composite matrices from group rings, composite G-codes and constructions of self-dual codes [PDF]

open access: yesDesigns, Codes and Cryptography, 2020
In this work, we define composite matrices which are derived from group rings. We extend the idea of G-codes to composite G-codes. We show that these codes are ideals in a group ring, where the ring is a finite commutative Frobenius ring and G is an ...

Unique Generators for Cyclic Codes of Arbitrary Length over Fpmu/u3 and Their Applications

open access: yesJournal of Mathematics, 2022
Cyclic codes play a very important role in the history of coding theory since they have good algebraic structures that can be widely used in coding and decoding.
