In this work, we present constructions of families of rotated $D_n$-lattices which may be good for signal transmission over both Gaussian and Rayleigh fading channels. The lattices are obtained as sublattices of a family of rotated $\mathbb{Z} \oplus

In this work, we present constructions of algebraic lattices in Euclidean space with optimal center density in dimensions 2,3,4,5,6,8 and 12, which are rotated versions of the lattices Lambda_n, for n =2,3,4,5,6,8 and K_12. These algebraic lattices a

Neste trabalho apresentamos uma forma traco associada ao subcorpo maximal real deQ(ζm). A forma traco e de suma importância para a obtencao de reticulados com alta densidade de empacotamento esferico, uma vez que a minimizacao desta forma, a qual e
