Duality and Reverse Self-Dual Constructions for Hyperderivative Reed-Solomon Codes
Hongchang Li, Zhihao Zhu, Weijun Fang +2
Hyperderivative Reed-Solomon (HRS) codes form a class of maximum-distance-separable codes under the Niederreiter-Rosenbloom-Tsfasman metric and may be viewed as a derivative-evalua…
Lower Bounds on Conversion Bandwidth for MDS Convertible Codes in Split Regime
Lewen Wang, Sihuang Hu
We propose several new lower bounds on the bandwidth costs of MDS convertible codes using a linear-algebraic framework. The derived bounds improve previous results in certain param…
Optimal Repair of MDS Array Codes
Zihao Zhang, Guodong Li, Sihuang Hu
Maximum distance separable (MDS) codes are widely used in distributed storage systems as they provide optimal fault tolerance for a given amount of storage overhead. The seminal wo…
Lower Bounds on the Sub-Packetization of Optimal-Access MSR Codes for Multiple-Node Repair
Lewen Wang, Zihao Zhang, Sihuang Hu
We establish lower bounds on the sub-packetization of optimal-access MSR codes in the context of multiple-node failures. These bounds generalize the tight bounds for single-node fa…
Constructing cooperative MSR codes with sub-packetization
Zihao Zhang, Guodong Li, Sihuang Hu
We address the multi-node failure repair challenges for MDS array codes. Presently, two primary models are employed for multi-node repairs: the centralized model where all failed n…
Optimal Locally Repairable Codes via Punctured Simplex Codes
Yuan Gao, Weijun Fang, Jingke Xu +2
Locally repairable codes (LRCs) have attracted a lot of attention due to their applications in distributed storage systems. In this paper, we provide new constructions of optimal $…
