The Generalized Lasso for Sub-gaussian Measurements with Dithered Quantization
Christos Thrampoulidis, Ankit Singh Rawat
In the problem of structured signal recovery from high-dimensional linear observations, it is commonly assumed that full-precision measurements are available. Under this assumption…
MDS Code Constructions with Small Sub-packetization and Near-optimal Repair Bandwidth
Ankit Singh Rawat, Itzhak Tamo, Venkatesan Guruswami +1
This paper addresses the problem of constructing MDS codes that enable exact repair of each code block with small repair bandwidth, which refers to the total amount of information…
A Note on Secure Minimum Storage Regenerating Codes
Ankit Singh Rawat
This short note revisits the problem of designing secure minimum storage regenerating (MSR) codes for distributed storage systems. A secure MSR code ensures that a distributed stor…
New MDS codes with small sub-packetization and near-optimal repair bandwidth
Venkatesan Guruswami, Ankit Singh Rawat
An vector code is a collection of codewords where elements (from the field ) in each of the codewords are referred…
Centralized Repair of Multiple Node Failures with Applications to Communication Efficient Secret Sharing
Ankit Singh Rawat, O. Ozan Koyluoglu, Sriram Vishwanath
This paper considers a distributed storage system, where multiple storage nodes can be reconstructed simultaneously at a centralized location. This centralized multi-node repair (C…
Progress on High-rate MSR Codes: Enabling Arbitrary Number of Helper Nodes
Ankit Singh Rawat, O. Ozan Koyluoglu, Sriram Vishwanath
This paper presents a construction for high-rate MDS codes that enable bandwidth-efficient repair of a single node. Such MDS codes are also referred to as the minimum storage regen…
