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…
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…
Some New Results on Sequence Reconstruction Problem for Deletion Channels
Xiang Wang, Weijun Fang, Han Li +1
Levenshtein first introduced the sequence reconstruction problem in . In the realm of combinatorics, the sequence reconstruction problem is equivalent to determining the valu…
Three Classes of Twisted Gabidulin Codes with Different Twists
Ran Li, Fang-Wei Fu, Weijun Fang
Twisted Gabidulin codes are an extension of Gabidulin codes and have recently attracted great attention. In this paper, we study three classes of twisted Gabidulin codes with diffe…
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…
