Hybrid RIS-Empowered Reflection and Decode-and-Forward Relaying for Coverage Extension
Ibrahim Yildirim, Fatih Kilinc, Ertugrul Basar +1
In this letter, we introduce two hybrid transmission schemes combining a passive reconfigurable intelligent surface (RIS) with decode-and-forward relaying in a synergistic manner.…
Reconfigurable Intelligent Surface-Assisted Uplink Sparse Code Multiple Access
Ibrahim Al-Nahhal, Octavia A. Dobre, Ertugrul Basar
Reconfigurable intelligent surface-empowered communication (RIS) and sparse code multiple access (SCMA) are promising candidates for future generations of wireless networks. The fo…
A Novel RIS-Assisted Modulation Scheme
Liang Yang, Fanxu Meng, Mazen O. Hasna +1
In this work, in order to achieve higher spectrum efficiency, we propose a reconfigurable intelligent surface (RIS)-assisted multi-user communication uplink system. Different from…
Exploiting Reconfigurable Intelligent Surfaces in Edge Caching: Joint Hybrid Beamforming and Content Placement Optimization
Yingyang Chen, Miaowen Wen, Ertugrul Basar +3
Edge caching can effectively reduce backhaul burden at core network and increase quality-ofservice at wireless edge nodes. However, the beneficial role of edge caching cannot be fu…
Reconfigurable Intelligent Surfaces for Future Wireless Networks: A Channel Modeling Perspective
E. Basar, I. Yildirim
While the researchers have set their sights on future wireless networks of 2030, communications through reconfigurable intelligent surfaces (RISs) appears as one of the potential e…
Super-Mode OFDM with Index Modulation
Ali Tugberk Dogukan, Ertugrul Basar
Orthogonal frequency division multiplexing (OFDM) with index modulation (OFDM-IM) appears as a promising multi-carrier waveform candidate for beyond 5G due to its attractive advant…
