RIS-Assisted Survivable Backhaul Recovery in Small-Cell Systems
Zhenyu Li, Özlem Tuğfe Demir, Emil Björnson +1
The increasing densification of small-cell networks substantially expands cable-based backhaul infrastructure, creating heightened vulnerability to cable link failures. This paper…
Feasibility Study Regarding Self-sustainable Reconfigurable Intelligent Surfaces
Zhenyu Li, Ozan Alp Topal, Özlem Tuğfe Demir +2
Without requiring operational costs such as cabling and powering while maintaining reconfigurable phase-shift capability, self-sustainable reconfigurable intelligent surfaces (ssRI…
RIS-Assisted Survivable Fronthaul Design in Cell-Free Massive MIMO System
Zhenyu Li, Özlem Tuğfe Demir, Emil Björnson +1
This paper investigates the application of reconfigurable intelligent surfaces (RISs) to improve fronthaul link survivability in cell-free massive MIMO (CF mMIMO) systems. To enhan…
Self-Sustainable Metasurface-Assisted mmWave Indoor Communication System
Zhenyu Li, Ozan Alp Topal, Özlem Tuğfe Demir +2
In the design of a metasurface-assisted system for indoor environments, it is essential to take into account not only the performance gains and coverage extension provided by the m…
Mixed Static and Reconfigurable Metasurface Deployment in Indoor Dense Spaces: How Much Reconfigurability is Needed?
Zhenyu Li, Ozan Alp Topal, Özlem Tuğfe Demir +2
In this paper, we investigate how metasurfaces can be deployed to deliver high data rates in a millimeter-wave (mmWave) indoor dense space with many blocking objects. These surface…
