Performance analysis of multiuser free space optical communications
Zhalehpour, Sasan (2014-08)Terrestrial Free Space Optical (FSO) communications involve using optical beams to carry information through atmospheric channels between two points. Unlike radio frequency (RF) communications, FSO systems are not burdened ... -
Performance analysis of quantum key distribution in underwater turbulence channels
The current literature on quantum key distribution (QKD) is mainly limited to the transmissions over ber optic, atmospheric or satellite links and are not directly applicable to underwater environments with di erent channel ... -
Performance analysis of vertical underwater visible light communication link
Yılmaz, Anıl (2018-07)Demand for high-bandwidth underwater applications such as image and real-time video transmission, has been increasing parallel to the increase in maritime activities such as environment monitoring, navigation, ocean-pollution ... -
Performance characterization of vehicular visible light communications
Karbalayghareh, Mehdi (2019-07-16)In Intelligent Transportation Systems (ITSs), visible light communication (VLC) has emerged as a powerful candidate to enable wireless connectivity in vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) links. VLC ... -
Relay-assisted OFDM-based visible light communications
Narmanlıoğlu, Ömer (2016-08)In this study, a relay-assisted visible light communication (VLC) system where an intermediate light source cooperates with the main light source is investigated. Specifically, two light sources in an office space; one is ... -
A simulation study of cooperative underwater acoustic communication
Sökün, Hamza Ümit (2012-08)Cooperative communication promises significant performance gains in terms of link reliability, spectral efficiency, system capacity, and transmission range. Due to its indisputable advantages for high-speed underwater ... -
Simultaneous lightwave information and power transfer in underwater visible light communications
In this thesis, we investigate simultaneous lightwave information and power transfer (SLIPT) for underwater visible light communication systems. We consider four SLIPT methods namely AC-DC separation (ADS), time switching ... -
Standard-compliant and software defined VLC system: implementation and performance evaluation
Hussain, Waqas (2015-08)LED lighting is now a cost-effective and energy-efficient technology for general-purpose illumination. Recent advances in LED lighting allow us to use LEDs not only for illumination but at the same time for wireless ... -
Two-stage broadband class-AB high power amplifier design using gan hemt technology
Modern radio systems need broadband, high efficiency power amplifiers to cover a wide frequency spectrum with reliable system performance. Linearity is another critical parameter in power amplifier design and there is a ... -
Ultraviolet communications for airborne links
Tadayyoniahrab, Hamed (2019-07)In Turkey, artificial insemination is only permitted to couples when they are officially married. Surrogacy, however, has been banned by the law and is illegal as in most European countries. Despite the fact that nowadays ... -
Wireless internet service providing for 5G with hybrid TV broadcast and visible light communications
Şencan, Sezgin (2018-01)Visible light communications (VLC) is a future promising communication technology to be utilized in future 5G networks satisfying energy efficient outdoor and indoor communications with existing hardware components such ...
