Deep Learning-based Power Allocation in Rate Splitting Optical Wireless Networks

no code implementations17 Jul 2023 Khulood D. Alazwary, Ahmad Adnan Qidan, T. E. H. El-Gorashi, Jaafar M. H. Elmirghani

In RS, the transmitted power is allocated to different messages, common and private messages, serving multiple users simultaneously, where each user can decode the desired message following a certain procedure.

Rate Splitting for 6G Optical Wireless Networks

no code implementations6 Apr 2023 Khulood D. Alazwary, Ahmad Adnan Qidan, T. E. H. El-Gorashi, Jaafar M. H. Elmirghani

This paper evaluates the performance of rate splitting (RS), a robust interference management scheme, in an optical wireless communication (OWC) network that uses infrared lasers referred to as vertical-cavity surface-emitting lasers (VCSELs) as optical transmitters.

Angle Diversity Trasmitter For High Speed Data Center Uplink Communications

no code implementations29 Oct 2021 Abrar S. Alhazmi, Sanaa H. Mohamed, Osama Z. Alsulami, T. E. H. El-Gorashi, Jaafar M. H. Elmirghani

We consider three racks in a data center where each rack contains an Angle Diversity Transmitter (ADT) positioned on the top of the rack to realize the uplink function of a top-of-the-rack (ToR) or a leaf switch.

Resource Allocation in 6G Optical Wireless Systems

no code implementations5 Aug 2020 Osama Zwaid Alsulami, T. E. H. El-Gorashi, Jaafar M. H. Elmirghani

In addition, the optimization of resource allocation is considered in this chapter by developing a mixed-integer linear programming (MILP) model that can be used to maximize the signal to noise and interference ratio (SINR) while supporting multiple users.

Impact of user distribution on optical wireless systems

no code implementations4 May 2020 Khulood D. Alazwary, Osama Zwaid Alsulami, Sarah O. M. Saeed, Sanaa Hamid Mohamed, T. E. H. El-Gorashi, Mohammed T. Alresheedi, Jaafar M. H. Elmirghani

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) scheme.

Data center top of rack switch to multiple spine switches optical wireless uplinks

no code implementations3 May 2020 Abrar S. Alhazmi, Osama Zwaid Alsulami, T. E. H. El-Gorashi, Mohammed T. Alresheedi, Jaafar M. H. Elmirghani

In our proposed data centre, we consider three racks, each of which has its own angle diversity transmitter (ADT) that is located on top of the rack.

Delay Adaptation Method for Relay Assisted Optical Wireless Systems

no code implementations30 Apr 2020 Yu Zeng, Sanaa Hamid Mohamed, T. E. H. El-Gorashi, Jaafar M. H. Elmirghani

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.
