Zero-Energy RIS-Assisted Communications With Noise Modulation and Interference-Based Energy Harvesting
Ahmad Massud Tota Khel, Aissa Ikhlef, Zhiguo Ding +1
To advance towards carbon-neutrality and improve the limited {performance} of conventional passive wireless communications, in this paper, we investigate the integration of noise m…
Sum-rate Maximization in Uplink CRAN with a Massive MIMO Fronthaul
Dick Maryopi, Yingjia Huang, Aissa Ikhlef
The limited fronthaul capacity is known to be one of the main problems in cloud radio access networks (CRANs), especially in the wireless fronthaul links. In this paper, we conside…
Optimal Downlink Transmission for Cell Free SWIPT Massive MIMO Systems with Active Eavesdropping
Mahmoud Alageli, Aissa Ikhlef, Fahad Alsifiany +3
This paper considers secure simultaneous wireless information and power transfer (SWIPT) in cell-free massive multiple-input multiple-output (MIMO) systems. The system consists of…
On Differential Modulation in Downlink Multiuser MIMO Systems
Fahad Alsifiany, Aissa Ikhlef, Jonathon Chambers
In this paper, we consider a space time block coded multiuser multiple-input multiple-output (MU-MIMO) system with downlink transmission. Specifically, we propose to use downlink p…
Power Allocation for Conventional and Buffer-Aided Link Adaptive Relaying Systems with Energy Harvesting Nodes
Imtiaz Ahmed, Aissa Ikhlef, Robert Schober +1
Energy harvesting (EH) nodes can play an important role in cooperative communication systems which do not have a continuous power supply. In this paper, we consider the optimizatio…
Buffers Improve the Performance of Relay Selection
Aissa Ikhlef, Diomidis S. Michalopoulos, Robert Schober
We show that the performance of relay selection can be improved by employing relays with buffers. Under the idealized assumption that no buffer is full or empty, the best source-re…
