Reconfigurable Intelligent Surface Optimal Placement in Millimeter-Wave Networks
Konstantinos Ntontin, Alexandros-Apostolos A. Boulogeorgos, Dimitrios Selimis +3
This work discusses the optimal reconfigurable intelligent surface placement in highly-directional millimeter wave links. In particular, we present a novel system model that takes…
Performance Evaluation of Reconfigurable Intelligent Surface Assisted D-band Wireless Communication
Evangelos N. Papasotiriou, Alexandros-Apostolos A. Boulogeorgos, Antigone Stratakou +1
In the recent years, the proliferation of wireless data traffic has led the scientific community to explore the use of higher unallocated frequency bands, such as the millimeter wa…
Ergodic capacity analysis of reconfigurable intelligent surface assisted wireless systems
Alexandros-Apostolos A. Boulogeorgos, Angeliki Alexiou
This paper presents the analytic framework for evaluating the ergodic capacity (EC) of the reconfigurable intelligent surface (RIS) assisted systems. Moreover, high-signal-to-noise…
Outage Probability Analysis of THz Relaying Systems
Alexandros-Apostolos A. Boulogeorgos, Angeliki Alexiou
This paper focuses on quantifying the outage performance of terahertz (THz) relaying systems. In this direction, novel closed-form expressions for the outage probability of a dual-…
A Low-Overhead Hierarchical Beam-tracking Algorithm for THz Wireless Systems
Giorgos Stratidakis, Georgia D. Ntouni, Alexandros-Apostolos A. Boulogeorgos +2
In this paper, a novel hierarchical beamtracking approach, which is suitable for terahertz (THz) wireless systems, is presented. The main idea is to employ a prediction based algor…
Relay-Based Blockage and Antenna Misalignment Mitigation in THz Wireless Communications
Giorgos Stratidakis, Evangelos N. Papasotiriou, Haralampos Konstantinis +2
The proliferation of wireless devices in recent years has caused a spectrum shortage, which led the scientific community to explore the potential of using terahertz (THz) communica…
