Near-Field Multipath MIMO Channels: Modeling Reflectors and Exploiting NLOS Paths
Mohamadreza Delbari, George C. Alexandropoulos, Robert Schober +2
Near-field (NF) communications is receiving renewed interest in the context of multiple-input multiple-output (MIMO) systems involving large physical apertures with respect to the…
Far- versus Near-Field RIS Modeling and Beam Design
Mohamadreza Delbari, George C. Alexandropoulos, Robert Schober +1
In this chapter, we investigate the mathematical foundation of the modeling and design of reconfigurable intelligent surfaces (RIS) in both the far- and near-field regimes. More sp…
Molecule Mixture Detection and Alphabet Design for Non-linear, Cross-reactive Receiver Arrays in MC
Bastian Heinlein, Kaikai Zhu, Sümeyye Carkit-Yilmaz +6
Air-based molecular communication (MC) has the potential to be one of the first MC systems to be deployed in real-world applications, enabled by existing sensor technologies such a…
Rejuvenating IRS: AoI-based Low Overhead Reconfiguration Design
Jorge Torres Gómez, Joana Angjo, Moritz Garkisch +3
Intelligent reflective surface (IRS) technologies help mitigate undesirable effects in wireless links by steering the communication signal between transmitters and receivers. IRS e…
Near-Field Multipath MIMO Channel Model for Imperfect Surface Reflection
Mohamadreza Delbari, George C. Alexandropoulos, Robert Schober +2
Near-field (NF) communications is receiving renewed attention in the context of passive reconfigurable intelligent surfaces (RISs) due to their potentially extremely large dimensio…
User Tracking and Direction Estimation Codebook Design for IRS-Assisted mmWave Communication
Moritz Garkisch, Sebastian Lotter, Gui Zhou +2
Future communication systems are envisioned to employ intelligent reflecting surfaces (IRSs) and the millimeter wave (mmWave) frequency band to provide reliable high-rate services.…
