The Minimum Subpacketization of Reed-Solomon Codes with Linear Repair Achieving the Cut-Set Bound

Weijun Fang, Jing Qiu, Shu-Tao Xia +1

In this paper, we study the minimum subpacketization of Reed-Solomon (RS) codes over admitting cut-set-optimal exact -linear repair of e…

Constructions of locally repairable codes via concatenated codes

Hengfeng Jin, Fang-Wei Fu

In recent years, locally repairable codes (LRCs) have attracted considerable attention owing to their pivotal role in distributed storage systems. Since binary linear locally repai…

Reed-Solomon Codes with Optimal Repair Bandwidth: A Basis-Transformation Approach

Jing Qiu, Weijun Fang, Shu-Tao Xia +1

Maximum distance separable (MDS) codes are widely used in distributed storage, but naively repairing a single failure in an MDS code requires downloading the full contents…

Construction of MDS Euclidean Self-Dual Codes via Multiple Subsets

Weirong Meng, Weijun Fang, Fang-Wei Fu +2

MDS self-dual codes have good algebraic structure, and their parameters are completely determined by the code length. In recent years, the construction of MDS Euclidean self-dual c…

New Lower Bounds for the Minimum Distance of Cyclic Codes and Applications to Locally Repairable Codes

Jing Qiu, Weijun Fang, Fang-Wei Fu

Cyclic codes are an important class of linear codes. Bounding the minimum distance of cyclic codes is a long-standing research topic in coding theory, and several well-known and ba…

Some new constructions of optimal linear codes and alphabet-optimal -locally repairable codes

Jing Qiu, Fang-Wei Fu

In distributed storage systems, locally repairable codes (LRCs) are designed to reduce disk I/O and repair costs by enabling recovery of each code symbol from a small number of oth…
