Energy-Efficient Soft-Assisted Product Decoders
Christoffer Fougstedt, Alireza Sheikh, Alexandre Graell i Amat +2
We implement a 1-Tb/s 0.63-pJ/bit soft-assisted product decoder in a 28-nm technology. The decoder uses one bit of soft information to improve its net coding gain by 0.2 dB, reachi…
A Droplet Approach Based on Raptor Codes for Distributed Computing With Straggling Servers
Albin Severinson, Alexandre Graell i Amat, Eirik Rosnes +2
We propose a coded distributed computing scheme based on Raptor codes to address the straggler problem. In particular, we consider a scheme where each server computes intermediate…
Local Reconstruction Codes: A Class of MDS-PIR Capacity-Achieving Codes
Siddhartha Kumar, Hsuan-Yin Lin, Eirik Rosnes +1
We prove that a class of distance-optimal local reconstruction codes (LRCs), an important family of repair-efficient codes for distributed storage systems, achieve the maximum dist…
Private Information Retrieval From a Cellular Network With Caching at the Edge
Siddhartha Kumar, Alexandre Graell i Amat, Eirik Rosnes +1
We consider the problem of downloading content from a cellular network where content is cached at the wireless edge while achieving privacy. In particular, we consider private info…
On the Fundamental Limit of Private Information Retrieval for Coded Distributed Storage
Hsuan-Yin Lin, Siddhartha Kumar, Eirik Rosnes +1
We consider private information retrieval (PIR) for distributed storage systems (DSSs) with noncolluding nodes where data is stored using a non maximum distance separable (MDS) lin…
On Low-Complexity Decoding of Product Codes for High-Throughput Fiber-Optic Systems
Alireza Sheikh, Alexandre Graell i Amat, Gianluigi Liva +2
We study low-complexity iterative decoding algorithms for product codes. We revisit two algorithms recently proposed by the authors based on bounded distance decoding (BDD) of the…
