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…
