Beamspace MIMO for Satellite Swarms
Maik Röper, Bho Matthiesen, Dirk Wübben +2
Systems of small distributed satellites in low Earth orbit (LEO) transmitting cooperatively to a multiple antenna ground station (GS) are investigated. These satellite swarms have…
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…
Machine Learning-Based 3D Channel Modeling for U2V mmWave Communications
Kai Mao, Qiuming Zhu, Maozhong Song +4
Unmanned aerial vehicle (UAV) millimeter wave (mmWave) technologies can provide flexible link and high data rate for future communication networks. By considering the new features…
Polarimetric Room Electromagnetics
Troels Pedersen, Ramoni Adeogun
A polarimetric model for the power delay spectrum for inroom communication is proposed. The proposed model describes the gradual depolarization of the signal with delay. The model…
Ground-Assisted Federated Learning in LEO Satellite Constellations
Nasrin Razmi, Bho Matthiesen, Armin Dekorsy +1
In Low Earth Orbit (LEO) mega constellations, there are relevant use cases, such as inference based on satellite imaging, in which a large number of satellites collaboratively trai…
Channel Estimation for RIS-Aided Multiuser Millimeter-Wave Systems
Gui Zhou, Cunhua Pan, Hong Ren +2
Channel estimation in the RIS-aided massive multiuser multiple-input single-output (MU-MISO) wireless communication systems is challenging due to the passive feature of RIS and the…
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…
Reconfigurable Intelligent Surfaces: A Signal Processing Perspective With Wireless Applications
Emil Björnson, Henk Wymeersch, Bho Matthiesen +3
Antenna array technology enables directional transmission and reception of wireless signals, for communications, localization, and sensing purposes. The signal processing algorithm…
