Towards a complete DMT classification of division algebra codes
Laura Luzzi, Roope Vehkalahti, Alexander Gorodnik
This work aims at providing new bounds for the diversity multiplexing gain trade-off of a general class of division algebra based lattice codes. In the low multiplexing gain regime…
Almost universal codes achieving ergodic MIMO capacity within a constant gap
Laura Luzzi, Roope Vehkalahti
This work addresses the question of achieving capacity with lattice codes in multi-antenna block fading channels when the number of fading blocks tends to infinity. A design criter…
Division algebra codes achieve MIMO block fading channel capacity within a constant gap
Laura Luzzi, Roope Vehkalahti
This work addresses the question of achieving capacity with lattice codes in multi-antenna block fading channels when the number of fading blocks tends to infinity. In contrast to…
Estimates for the growth of inverse determinant sums of quasi-orthogonal and number field lattices
Roope Vehkalahti, Laura Luzzi
Inverse determinant sums appear naturally as a tool for analyzing performance of space-time codes in Rayleigh fading channels. This work will analyze the growth of inverse determin…
