Non-binary LDPC codes for Data Storage
Irina Bocharova, Boris Kudryashov, Henk D. L. Hollmann +1
In modern data storage systems, non-binary LDPC codes for recovering from disk failures are increasingly considered strong competitors to MDS codes such as Reed-Solomon codes. Sinc…
Recovery Models for Linear Batch Codes
Baran Düzgün, Henk D. L. Hollmann, Ago-Erik Riet +2
Various types of recovery algorithms for batch codes have been considered previously, including asynchronous recovery and recovery algorithms arising from Almost Affinely Disjoint…
On the Minimum Length of Functional Batch Codes with Small Recovery Sets
Kristiina Oksner, Henk D. L. Hollmann, Ago-Erik Riet +1
Batch codes are of potential use for load balancing and private information retrieval in distributed data storage systems. Recently, a special case of batch codes, termed functiona…
PIR Codes, Unequal-Data-Demand Codes, and the Griesmer Bound
Henk D. L. Hollmann, Martin Puškin, Ago-Erik Riet
Unequal Error-Protecting (UEP) codes are error-correcting (EC) codes designed to protect some parts of the encoded data better than other parts. Here, we introduce a similar genera…
