Deep Reinforcement Learning for Optimizing RIS-Assisted HD-FD Wireless Systems
Alice Faisal, Ibrahim Al-Nahhal, Octavia A. Dobre +1
This letter investigates the reconfigurable intelligent surface (RIS)-assisted multiple-input single-output (MISO) wireless system, where both half-duplex (HD) and full-duplex (FD)…
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…
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…
Modified zero forcing decoder for ill-conditioned channels
Ibrahim Al-Nahhal, Masoud Alghoniemy, Adel B. Abd El-Rahman +1
A modified zero-forcing (MZF) decoder for ill-conditioned Multi-Input Multi-Output (MIMO) channels is proposed. The proposed decoder provides significant performance improvement co…
Low-Cost Uplink Sparse Code Multiple Access for Spatial Modulation
Ibrahim Al-Nahhal, Octavia A. Dobre, Ertugrul Basar +1
Spatial modulation (SM)-sparse code multiple access (SCMA) systems provide high spectral efficiency (SE) at the expense of using a high number of transmit antennas. To overcome thi…
