Optimal Ferrers Diagram Rank-Metric Codes: New Constructions, Diagram Combinations, and Applications to Constant-Dimension Subspace Codes
Fang-Wei Fu, Xuan Gao, Sihem Mesnager +1
In this paper, we present three new constructions of optimal FDRM codes, all derived from subcodes of maximum rank-distance (MRD) codes. The first construction (Theorem~\ref{theo5}…

Multilevel inserting constructions for constant dimension subspace codes
Gang Wang, Xuan Gao, Sihem Mesnager +1
Subspace codes, especially constant dimension subspace codes (CDCs), represent an intriguing domain that can be used to conduct basic coding theory investigations. They have receiv…
