Analysis and optimization of the network throughput in ieee 802.15.13 based visible light communication networks
In recent years, commercialization of visible light communication networks have started. As a result, there are multiple groups working for their standardization. In this work, we focus on one of them, which is IEEE 802.15 ... -
Multi-resampling doppler compensation in cooperative underwater OFDM systems
Karakaya, B.; Hasna, M. O.; Duman, T. M.; Uysal, Murat; Ghrayeb, A. (IEEE, 2013)We consider a multi-carrier cooperative underwater acoustic communication (UWAC) system and investigate the Doppler scaling problem arising due to the motion of different nodes. Specifically, we assume an orthogonal frequency ... -
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 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 selection for cooperative underwater acoustic communication systems
Karakaya, B.; Hasna, M. O.; Uysal, Murat; Duman, T. M.; Ghrayeb, A. (IEEE, 2012)In this paper, we consider a multi-carrier and multi-relay underwater acoustic communication (UWAC) system and investigate the relay selection problem. Our channel model is built on an aggregation of both large-scale path ... -
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 ... -
Sualtı akustik haberleşmesi için SNR tabanlı röle seçimi kullanan işbirlikli OFDM sistemleri
Karakaya, B.; Sökün, Hamza Ümit; Uysal, Murat; Hasna, M. O. (IEEE, 2012)In this paper, we investigate a multi-carrier multi-relay cooperative system with amplify-and-forward relaying over frequency-selective underwater acoustic channels. Relay selection rules rely on the maximization of ... -
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 ...
