A class of multilevel error-correcting codes
Valdemar C. da Rocha · International Journal of Electronics · 1981
A systematic procedure for constructing multilevel codes is presented. These are pseudocyclic random error-correcting codes with p m symbols, where p is a primo number. Some examples are given including a class of maximum distance separable double-error-correcting codes. These codes can be decoded in a way similar to cyclic codes.
