Coordinated interference management for visible light communication systems
Kashef, M.; Abdallah, M.; Qaraqe, K.; Haas, H.; Uysal, Murat (IEEE, 2015-11)In this paper, we consider the performance of a visible light communication (VLC) network with coordinated interference management. The VLC transmitters are allowed to coordinate their transmissions using one of two ... -
Effect of eddy diffusivity ratio on underwater optical scintillation index
Elamassie, Mohammed; Uysal, Murat; Baykal, Y.; Abdallah, M.; Qaraqe, K. (The Optical Society, 2017-10-11)The performance of underwater optical wireless communication systems is severely affected by the turbulence that occurs due to the fluctuations in the index of refraction. Most previous studies assume a simplifying, yet ... -
The impact of location errors on achievable rates in OFDM-based multi-user visible light communication systems
Kashef, M.; Abdallah, M.; Qaraqe, K.; Uysal, Murat (IEEE, 2014)Visible light communication (VLC) is a communication technology in which data is transferred by modulating the visible light intensity. VLC signals degrade significantly due to the absence of the line of sight (LOS) between ... -
Indoor channel modelling and characterization for visible light communications
Sarbazi, Elham; Uysal, Murat; Abdallah, M.; Qaraqe, K. (IEEE, 2014)In this paper, we investigate channel modeling for visible light communications using ray tracing approach. The simulation environment is created in Zemax® and enables us to specify the geometry of the environment, the ... -
On the benefits of cooperation via power control in OFDM-based visible light communication systems
Kashef, M.; Abdallah, M.; Qaraqe, K.; Haas, H.; Uysal, Murat (IEEE, 2014)In this paper, the performance of a visible light communication (VLC) network exploiting power control is considered. The achievable rate region of two VLC communication pairs is characterized. The system employs optical ... -
Performance evaluation of LOS and NLOS vertical inhomogeneous links in underwater visible light communications
Anous, N.; Abdallah, M.; Uysal, Murat (IEEE, 2018-03-22)In this paper, underwater visible light communication (UWVLC) vertical links are modeled and evaluated, taking account of the inhomogeneous nature of underwater (UW) environment. An equivalent simplified model of stratified ... -
Ray tracing based channel modeling for visible light communications
Sarbazi, Elham; Uysal, Murat; Abdallah, M.; Qaraqe, K. (IEEE, 2014)Bu bildiride, Zemax 13 yazılımı aracılığı ile görünür ışık haberleşmesi (visible light communication, VLC) kanalları karakterize edilecektir. Yaklaşımımızda, ölçülerini tanımlayacağımız iç mekân ortamı üçboyutlu olarak ... -
Resource allocation for downlink OFDMA in underwater visible light communications
Elamassie, Mohammed; Karbalayghareh, Mehdi; Miramirkhani, Farshad; Uysal, Murat; Abdallah, M.; Qaraqe, K. (IEEE, 2019-06)As a wireless connectivity solution with low latency and high capacity, visible light communication (VLC) is particularly attractive for high-speed underwater applications such as image or real-time video transmission. In ... -
Single photon avalanche diode (SPAD) VLC system and application to downhole monitoring
Li, Y.; Videv, S.; Abdallah, M.; Qaraqe, K.; Uysal, Murat; Haas, H. (IEEE, 2014)In this paper, it is demonstrated for the first time that the problem of continuous downhole monitoring in the oil and gas industry is effectively addressed by the use of visible light communication (VLC). As a reliable, ... -
Visible light channel modeling for gas pipelines
Miramirkhani, Farshad; Uysal, Murat; Narmanlıoğlu, Ömer; Abdallah, M.; Qaraqe, K. (IEEE, 2018-04)In this paper, we explore the use of visible light communication as a means of wireless monitoring in gas pipelines. In an effort to shed light on the communication limits in the presence of gas, we create a three-dimensional ...
