Construction of full diversity D_n-lattices for all n

In this paper we construct some families of rotated $D_n$-lattices with full diversity for any $n$. These lattices can be good for signal transmission over both Gaussian and Rayleigh fading channels. In order to get bounds for their minimum product distances, we show that the $Z$-modules used in \cite{sethoggier} to obtain rotated $\mathbb{Z}^{n}$-lattices with $n$ odd are ideals and find a sufficient condition for such ideals being principal ideals.
