RIS-Aided RSMA Improves the Latency vs. Energy Trade-off in the Finite Block Length MIMO Downlink
Mohammad Soleymani, Bruno Clerckx, Robert Schober +1
We simultaneously minimize the latency and improve energy efficiency (EE) of the multi-user multiple-input multiple-output (MU-MIMO) rate splitting multiple access (RSMA) downlink,…
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…
DiffPace: Diffusion-based Plug-and-play Augmented Channel Estimation in mmWave and Terahertz Ultra-Massive MIMO Systems
Zhengdong Hu, Chong Han, Wolfgang Gerstacker +1
Millimeter-wave (mmWave) and Terahertz (THz)-band communications hold great promise in meeting the growing data-rate demands of next-generation wireless networks, offering abundant…
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…
Wireless Energy Transfer Beamforming Optimization for Intelligent Transmitting Surface
Osmel MartÃnez Rosabal, Onel Alcaraz López, Victoria Dala Pegorara Souto +4
Radio frequency (RF) wireless energy transfer (WET) is a promising technology for powering the growing ecosystem of Internet of Things (IoT) using power beacons (PBs). Recent resea…
MC for Agriculture: A Framework for Nature-inspired Sustainable Pest Control
Fardad Vakilipoor, Nora Hirschmann, Julian Schladt +5
In agriculture, molecular communication (MC) is envisioned as a framework to address critical challenges such as smart pest control. While conventional approaches mostly rely on sy…
