Number field lattices achieve Gaussian and Rayleigh channel capacity within a constant gap
Roope Vehkalahti, Laura Luzzi
This paper proves that a family of number field lattice codes simultaneously achieves a constant gap to capacity in Rayleigh fast fading and Gaussian channels. The key property in…

Shifted inverse determinant sums and new bounds for the DMT of space-time lattice codes
Roope Vehkalahti, Laura Luzzi, Jean-Claude Belfiore
This paper considers shifted inverse determinant sums arising from the union bound of the pairwise error probability for space-time codes in multiple-antenna fading channels. Previ…
