Reconfigurable Intelligent Surface Optimization for Uplink Sparse Code Multiple Access
Ibrahim Al-Nahhal, Octavia A. Dobre, Ertugrul Basar +2
The reconfigurable intelligent surface (RIS)-assisted sparse code multiple access (RIS-SCMA) is an attractive scheme for future wireless networks. In this letter, for the first tim…
On the Complexity Reduction of Uplink Sparse Code Multiple Access for Spatial Modulation
Ibrahim Al-Nahhal, Octavia A. Dobre, Salama Ikki
Multi-user spatial modulation (SM) assisted by sparse code multiple access (SCMA) has been recently proposed to provide uplink high spectral efficiency transmission. The message pa…
Reliable Detection for Spatial Modulation Systems
Ibrahim Al-Nahhal, Octavia A. Dobre, Salama Ikki
Spatial modulation (SM) is a promising multiple-input multiple-output system used to increase spectral efficiency. The maximum likelihood (ML) decoder jointly detects the transmitt…
Localization Error Bounds For 5G mmWave Systems Under I/Q Imbalance: An Extended Version
Fariba Ghaseminajm, Zohair Abu-Shaban, Salama S. Ikki +2
