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…
On some batch code properties of the simplex code
Henk D. L. Hollmann, Karan Khathuria, Ago-Erik Riet +1
The binary -dimensional simplex code is known to be a -batch code and is conjectured to be a -functional batch code. Here, we offer a simple, constructive proo…
NB QC-LDPC Coded QAM Signals with Optimized Mapping: Bounds and Simulation Results
Irina E. Bocharova, Boris D. Kudryashov, Evgenii P. Ovsyannikov +1
The goal of the paper is to study specific properties of nonbinary low-density parity-check (NB LDPC) codes when used in coded modulation systems. The paper is focused on the pract…
Failure Probability Analysis for Partial Extraction from Invertible Bloom Filters
Ivo Kubjas, Vitaly Skachek
Invertible Bloom Filter (IBF) is a data structure, which employs a small set of hash functions. An IBF allows for an efficient insertion and, with high probability, for an efficien…
