Improved bounds and singleton-optimal constructions of locally repairable codes with minimum distance 5 and 6
Repair locality has been an important metric in a distributed storage system (DSS). Erasure
codes with small locality are more popular in a DSS, which means fewer available nodes …

Constructions and bounds for subspace codes
S Kurz - arxiv preprint arxiv:2112.11766, 2021 - arxiv.org
Subspace codes are the $ q $-analog of binary block codes in the Hamming metric. Here the
codewords are vector spaces over a finite field. They have eg applications in random linear …

Bounds and constructions of singleton-optimal locally repairable codes with small localities
An-locally repairable code (LRC) is called a Singleton-optimal LRC if it achieves the
Singleton-type bound. Analogous to the classical MDS conjecture, the maximal length …
