Abstract
In this paper we present a method for evaluating the center density of algebraic lattices from subflelds of Q(xin), where n is a positive integer. This method allows to reproduce rotated versions of dense lattices in some dimensions. Constellations on algebraic lattices with high packing density have been proposed for use in communications in Gaussian channels and also in Rayleigh fading channels in case they have high diversity.
