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…
Angle Diversity Trasmitter For High Speed Data Center Uplink Communications
Abrar S. Alhazmi, Sanaa H. Mohamed, Osama Z. Alsulami +2
This paper proposes an uplink optical wireless communication (OWC) link design that can be used by data centers to support communication in spine and leaf architectures between the…
Impact of user distribution on optical wireless systems
Khulood D. Alazwary, Osama Zwaid Alsulami, Sarah O. M. Saeed +4
In this paper, we investigate the impact of user distribution on resource allocation in visible light communication (VLC) systems, using a wavelength division multiple access (WDMA…
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…
Resilience in Optical Wireless Systems
Sarah O. M. Saeed, Sanaa Hamid Mohamed, Osama Zwaid Alsulami +3
High reliability and availability of communication services is a key requirement that needs to be ensured by service providers. Since the direct line-of-sight (LOS) beam is prone t…
