Alternative names: Mixed-alphabet code.
Description
Encodes \(K\) states (codewords) in a string of two or more coordinates, each of which takes values in one of two or more possible groups.Protection
The Hamming, Singleton, and Plotkin bounds are straightforwardly extended to mixed alphabets [1; Thm. 5.1].Cousins
- Orthogonal array (OA)— Orthogonal arrays generalized to mixed alphabets are called mixed-level orthogonal arrays [2,3], (see [4; Ch. 9]). See Ref. [5] for bounds on mixed orthogonal arrays.
- Combinatorial design— Combinatorial designs have been generalized to mixed alphabets [6].
