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.…
Uplink Achievable Rate Maximization for Reconfigurable Intelligent Surface Aided Millimeter Wave Systems with Resolution-Adaptive ADCs
Yue Xiu, Jun Zhao, Ertugrul Basar +4
In this letter, we investigate the uplink of a reconfigurable intelligent surface (RIS)-aided millimeter-wave (mmWave) multi-user system. In the considered system, however, problem…
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…
