Centralized light access network (C-LiAN): a novel paradigm for next generation indoor VLC networks
Kizilirmak, R. Ç.; Narmanlıoğlu, Ömer; Uysal, Murat (IEEE, 2017)Visible light communication (VLC) builds upon the idea of using existing lighting infrastructure for wireless data transmission. In a conventional VLC network, each light fixture acts as an access point (AP) which are ... -
Cooperative visible light communications with full-duplex relaying
Narmanlıoğlu, Ömer; Kizilirmak, R. Ç.; Miramirkhani, Farshad; Uysal, Murat (IEEE, 2017-06)In this paper, we investigate cooperative visible light communication (VLC) system where an intermediate light source acts as a relay terminal. We assume that relay terminal operates in full-duplex mode. In contrast to ... -
FSO link attenuation measurement in extreme winter conditions for secure 5G applications
Khamidullin, A.; Kizilirmak, R. Ç.; Uysal, Murat; Ukaegbu, I. A. (SPIE, 2023)The functionality of Free Space Optical (FSO) communication links is highly influenced by meteorological conditions such as precipitation, snowfall, and fog. In this study, we establish an FSO link and conduct experimental ... -
Pilot-aided channel estimation on SC-PAM based visible light communications
Narmanlıoğlu, Ömer; Turan, B.; Kizilirmak, R. Ç.; Ergen, S. C.; Uysal, Murat (IEEE, 2018-07-02)Estimation of the time-varying optical wireless channel response is crucial in order to decode received signals coherently. In this work, we investigate symbol-error-rate and mean absolute error performance of different ... -
Unmanned-aerial-vehicle-assisted cooperative communications for visible light communications-based vehicular networks
Kalikulov, N.; Kizilirmak, R. Ç.; Uysal, Murat (SPIE, 2019-08)We propose and investigate cooperative visible light communications (VLC) enabled vehicular network architecture with an unmanned aerial vehicle (UAV) relay. In the proposed system, a UAV equipped with an onboard photodetector ...
