Such constellations are obtained via the ring of algebraic integers of an extension K=Q(√d) of Q, Where d=-1 or d=-3. The associated lattice constellations are suitable for Rayleigh fading channels because of their high spectral efficiency. © 1997 IEEE.391engTrabalho apresentado em evento10.1109/ISIT.1997.6133282-s2.0-0030701810
