Downlink MIMO Systems Using Cooperation Among Base Stations in a Slow Fading Channel
To increase the achievable sum rate of downlink MIMO (Multiple Input Multiple Output) systems, the cooperation among Base Stations (BS) is investigated in a slow fading channel. Th...

Outage-optimal transmission in multiuser-MIMO Kronecker channels
In this work, we look at single user and multiuser Multiple-Input Multiple-Output (MIMO) beamforming networks with Channel Distribution Information (CDI). CDI does not need to be ...
