DOI: 10.1109/tit.2020.3008342
Abstract: We consider the problem of multiple-node repair in distributed storage systems under the cooperative model, where the repair bandwidth includes the amount of data exchanged between any two different storage nodes. Recently, explicit constructions of… read more here.

DOI: 10.1109/tit.2020.3036386
Abstract: In the literature, all the known high-rate MDS codes with the optimal repair bandwidth possess a significantly large sub-packetization level, which may prevent the codes to be implemented in practical systems. To build MDS codes… read more here.
