Integrating RIS into HAP Networks for Improved Connectivity
Islam M. Tanash, Ayush Kumar Dwivedi, Taneli Riihonen
This paper investigates a high-altitude platform (HAP) network enhanced with reconfigurable intelligent surfaces (RISs). The arbitrary placement of HAPs and RISs is modeled using s…
In-Band Full-Duplex MIMO Systems for Simultaneous Communications and Sensing: Challenges, Methods, and Future Perspectives
Besma Smida, George C. Alexandropoulos, Taneli Riihonen +1
In-band Full-Duplex (FD) Multiple-Input Multiple-Output (MIMO) systems offer a significant opportunity for Integrated Sensing and Communications (ISAC) due to their capability to r…
Enhancing HAP Networks with Reconfigurable Intelligent Surfaces
Islam M. Tanash, Ayush Kumar Dwivedi, Fatemeh Rafiei Maleki +1
This paper presents and analyzes a reconfigurable intelligent surface (RIS)-based high-altitude platform (HAP) network. Stochastic geometry is used to model the arbitrary locations…
Analog Beamforming for In-Band Full-Duplex Phased Arrays with Quantized Phase Shifters under a Per-Antenna Received Power Constraint
Ao Liu, Ian P. Roberts, Taneli Riihonen +1
This letter develops a novel transmit beamforming (BF) design for canceling self-interference (SI) in analog in-band full-duplex phased arrays. Our design maximizes transmit BF gai…
