Add to ORKGAbstract: Signal constellations for representing data values for transmission benefit from shaping of the constell* tion boundary. In the Voronoi constellations, the Voronoi region of a lattice, denoted as the shaping lattice, is used as the boundary of the signal constellation. In this work, some properties of the Voronoi constellations based on the shaping lattices DN and DN are discussed. The induced probability distribution on the two dimensional subspaces is found. A prefix coding scheme as an alternative for the addressing is presented. This code in some sense simulates the effect of the boundary by using the points of the subspaces with nonequal probability.
