An algorithm is presented to find constellations with minimum average energy from a given lattice. For comparison, a numerical table of lattice constellations and group codes is computed for spaces of dimension two, three, and four. © 2001.271-280engAlgebraic latticeLinear labelingSignal constellationOn the Optimality of Finite Constellations from Algebraic LatticesArtigo10.1016/S1571-0653(04)00178-7Acesso restrito2-s2.0-342473654792-s2.0-52549131351
