Erasure coding for distributed storage: An overview
In a distributed storage system, code symbols are dispersed across space in nodes or
storage units as opposed to time. In settings such as that of a large data center, an important …

Explicit construction of optimal locally recoverable codes of distance 5 and 6 via binary constant weight codes
L ** - IEEE Transactions on Information Theory, 2019 - ieeexplore.ieee.org
In a paper by Guruswami et al., it was shown that the length n of a q-ary linear locally
recoverable code with distance d≥ 5 is upper bounded by O (dq 3). Thus, it is a challenging …
