Orthogonal SC-LDPC Codes for the IDS Channel
Frederik Walter, Jessica Bariffi, Antonia Wachter-Zeh
We propose a coding scheme for the insertion, deletion and substitution (IDS) channel tailored to the short strands of DNA-based data storage. Instead of an inner synchronisation c…
Probabilistic GC-Constraints for Composite DNA
Humeyra Bodur, Frederik Walter, Antonia Wachter-Zeh
This paper addresses the challenge of encoding biochemical GC-content constraints in composite DNA-based data storage. Previous deterministic models impose high rate penalties by a…
Coding Schemes for Document Exchange under Multiple Substring Edits
Hrishi Narayanan, Vinayak Ramkumar, Rawad Bitar +1
We study the document exchange problem under multiple substring edits. A substring edit in a string occurs when a substring of is replaced by…
On the Extension of Private Distributed Matrix Multiplication Schemes to the Grid Partition
Christoph Hofmeister, Razane Tajeddine, Antonia Wachter-Zeh +1
We consider polynomial codes for private distributed matrix multiplication (PDMM/SDMM). Existing codes for PDMM are either specialized for the outer product partitioning (OPP), or…
Coding Schemes for the Noisy Torn Paper Channel
Frederik Walter, Maria Abu-Sini, Nils Weinhardt +1
To make DNA a suitable medium for archival data storage, it is essential to consider the decay process of the strands observed in DNA storage systems. This paper studies the decay…
Multi-Terminal Remote Generation and Estimation Over a Broadcast Channel With Correlated Priors
Maximilian Egger, Rawad Bitar, Antonia Wachter-Zeh +2
We study the multi-terminal remote estimation problem under a rate constraint, in which the goal of the encoder is to help each decoder estimate a function over a certain distribut…
