Galois geometries and coding theory

T Etzion, L Storme - Designs, Codes and Cryptography, 2016 - Springer
Galois geometries and coding theory are two research areas which have been interacting
with each other for many decades. From the early examples linking linear MDS codes with …

PIR array codes with optimal PIR rates

SR Blackburn, T Etzion - 2017 IEEE International Symposium …, 2017 - ieeexplore.ieee.org

a database is stored across several servers using coding techniques from distributed …

Locality and availability of array codes constructed from subspaces

N Silberstein, T Etzion… - IEEE Transactions on …, 2018 - ieeexplore.ieee.org
We study array codes which are based on subspaces of a linear space over a finite field,
using spreads, q-Steiner systems, and subspace transversal designs. We present several …

On equidistant single-orbit cyclic and quasi-cyclic subspace codes

Mahak, M Bhaintwal - Designs, Codes and Cryptography, 2025 - Springer
A code is said to be equidistant if the distance between any two distinct codewords of the
code is the same. In this paper, we have studied equidistant single-orbit cyclic and quasi …

Recovery Sets of Subspaces from a Simplex Code

YM Chee, T Etzion, HM Kiah… - IEEE Transactions on …, 2024 - ieeexplore.ieee.org
Recovery sets for vectors and subspaces are important in the construction of distributed
storage system codes. These concepts are also interesting in their own right. In this paper …

Functional repair codes: a view from projective geometry

SL Ng, MB Paterson - Designs, Codes and Cryptography, 2019 - Springer
Storage codes are used to ensure reliable storage of data in distributed systems; functional
repair codes have the additional property that individual storage nodes that fail may be …

Multi-twisted codes over finite fields and their generalizations

V Chauhan, A Sharma - 2021 - repository.iiitd.edu.in
Nowadays error-correcting codes are widely used in communication systems, returning

Codes with locality in the rank and subspace metrics

S Kadhe, S El Rouayheb, I Duursma… - IEEE Transactions on …, 2019 - ieeexplore.ieee.org
We extend the notion of locality from the Hamming metric to the rank and subspace metrics.
Our main contribution is to construct a class of array codes with locality constraints in the …
