Multiuser beam steering OWC system based on NOMA
Y. Zeng, Sanaa H. Mohamed, Ahmad Qidan +2
In this paper, we propose applying Non-Orthogonal Multiple Access (NOMA) technology in a multiuser beam steering OWC system. We study the performance of the NOMA-based multiuser be…
Relay Assisted Multiuser OWC Systems under Human Blockage
Y. Zeng, Sanaa H. Mohamed, Ahmad Qidan +2
This paper proposes using cooperative communication based on optoelectronic (O-E-O) amplify-and-forward relay terminals to reduce the influence of the blockage and shadowing result…
Delay Adaptation Method for Relay Assisted Optical Wireless Systems
Yu Zeng, Sanaa Hamid Mohamed, T. E. H. El-Gorashi +1
In this paper, we investigate optical wireless repeaters as relay terminals between a transmitter and a user in an Infrared Optical Wireless Communication (IROWC) system. A delay a…
Energy Efficient virtualization framework for 5G F-RAN
Yu Zeng, Ahmed Al-Quzweeni, Taisir E. H. Elgorashi +1
Fog radio access network (F-RAN) and virtualisation are promising technologies for 5G networks. In F-RAN, the fog and cloud computing are integrated where the conventional C-RAN fu…
