Abstract :
A dyadic code is a code which is closed under all dyadic shifts. A quasicyclic dyadic (QCD) code is one which is both quasicyclic and dyadic. We obtain a simple characterization of all QCD codes over any field of odd characteristic using the Walsh-Hadamard transform defined over that field
