Statistics of the Effective Massive MIMO Channel in Correlated Rician Fading
Jens Abraham, Pablo Ramirez-Espinosa, Torbjörn Ekman
Massive MIMO base stations use multiple spatial diversity branches, which are often assumed to be uncorrelated in theoretical work. Correlated branches are considered seldom since…

Energy-Efficient 3D Deployment of Aerial Access Points in a UAV Communication System
Nithin Babu, Constantinos B. Papadias, Petar Popovski
In this letter, we propose an energy-efficient 3-dimensional placement of multiple aerial access points (AAPs), in the desired area, acting as flying base stations for uplink commu…
