Alternative names: Optimal rank-distance code.
Description
An \([n\times m,k,d]_q\) rank-metric code whose parameters are such that the Singleton-like bound \begin{align} k \leq \max(n, m) (\min(n, m) - d + 1) \tag*{(1)}\end{align} becomes an equality.Cousins
- Maximum distance separable (MDS) code— MRD codes are matrix-code analogues of MDS codes.
- Reed-Solomon (RS) code— MRD rank-metric codes can be thought of as matrix analogues of MDS RS codes as both constructions utilize a Vandermonde matrix [4].
- Gabidulin code— Gabidulin codes over \(\mathbb{F}_{q^N}\) with maximum rank-distance, when expressed as matrices over \(\mathbb{F}_q\), are MRD codes.
