Webb15 okt. 2006 · Abstract: In this paper, we study properties of rank metric codes in general and maximum rank distance (MRD) codes in particular. For codes with the rank metric, we first establish Gilbert and sphere-packing bounds, and then obtain the asymptotic forms of these two bounds and the Singleton bound. Webb1 aug. 2024 · Among rank-metric codes, of particular interest is the family of maximum rank distance (MRD)codes. These are codes that have optimal parameters: for the given …
WebbSuch a linear rank metric code always satisfies the Singleton bound [math]\displaystyle{ d \leq n - k + 1 }[/math]. Generating matrix. There are several known constructions of rank … In coding theory, rank codes (also called Gabidulin codes) are non-binary linear error-correcting codes over not Hamming but rank metric. They described a systematic way of building codes that could detect and correct multiple random rank errors. By adding redundancy with coding k-symbol word to a n-symbol word, a rank code can correct any errors of rank up to t = ⌊ (d − 1) / 2 ⌋, where d is a code distance. As an erasure code, it can correct up to d − 1 known erasures.
WebbThis construction is based on maximum rank distance (MRD) Gabidulin codes, which are a rank-metric analog of Reed-Solomon codes. The scalar and vector LRCs that are obtained by this construction are the first explicit optimal locally repairable codes with (r+δ− 1) ∤ n.
