Abstract
A Voronoi signal constellation includes those points of a coset of a lattice .LAMBDA. that lie within a Voronoi region of a sublattice .LAMBDA.' of .LAMBDA., where .LAMBDA.' is other than a scaled version of .LAMBDA.. The Voronoi signal constellation is combined with a coset code. A method of mapping data words to Voronoi constellation points is described.
