A Family of Almost MDS Symbol-Pair Codes of Length 8p

open access: yesIEEE Access
In high-density data storage systems, symbol-pair codes are commonly used to prevent symbol-pair errors. Designing maximum distance separable (MDS) codes is crucial in symbol-pair coding theory because MDS symbol-pair codes are the best at meeting the ...

Decoding of Convolutional Codes over the Erasure Channel

open access: yes, 2011
In this paper we study the decoding capabilities of convolutional codes over the erasure channel. Of special interest will be maximum distance profile (MDP) convolutional codes. These are codes which have a maximum possible column distance increase.

Decoding of MDP Convolutional Codes over the Erasure Channel under Linear Systems Point of View

open access: yesMathematics
This paper attempts to highlight the decoding capabilities of MDP convolutional codes over the erasure channel by defining them as discrete linear dynamical systems, with which the controllability property and the observability characteristics of linear ...

Genetic Algorithm-Based Method for Discovering Involutory MDS Matrices

open access: yesComputational and Mathematical Methods, 2023
In this paper, we present an innovative approach for the discovery of involutory maximum distance separable (MDS) matrices over finite fields F2q, derived from MDS self-dual codes, by employing a technique based on genetic algorithms. The significance of

Repair Scheduling in Wireless Distributed Storage with D2D Communication [PDF]

open access: yes, 2015
We consider distributed storage (DS) for a wireless network where mobile devices arrive and depart according to a Poisson random process. Content is stored in a number of mobile devices, using an erasure correcting code.

Parallel Concatenation of Non-Binary Linear Random Fountain Codes with Maximum Distance Separable Codes [PDF]

open access: yesIEEE Transactions on Communications, 2013
The performance and the decoding complexity of a novel coding scheme based on the concatenation of maximum distance separable (MDS) codes and linear random fountain codes are investigated.

Constructions of k-uniform and absolutely maximally entangled states beyond maximum distance codes

open access: yesPhysical Review Research, 2020
Pure multipartite quantum states of n parties and local dimension q are called k-uniform if all reductions to k parties are maximally mixed. These states are relevant for our understanding of multipartite entanglement, quantum information protocols, and ...

Complete Characterizations of Optimal Locally Repairable Codes With Locality 1 and $K-1$

open access: yesIEEE Access, 2019
A locally repairable code (LRC) is a [n, k, d] linear code with length n, dimension k, minimum distance d and locality r, which means that every code symbol can be repaired by at most r other symbols.

Maximum distance separable codes to order

open access: yes, 2019
Maximum distance separable (MDS) are constructed to required specifications. The codes are explicitly given over finite fields with efficient encoding and decoding algorithms. Series of such codes over finite fields with ratio of distance to length approaching $(1-R)$ for given $R, \, 0 < R < 1$ are derived.

An Optimal Recovery Approach for Liberation Codes in Distributed Storage Systems

open access: yesIEEE Access, 2020
To reduce the storage cost, distributed storage systems are gradually using erasure codes to ensure data reliability. Liberation codes, which satisfy the maximum distance separable (MDS) property and provide optimal modification overhead, are a class of ...
