Channel modelling and performance limits of vehicular visible light communication systems
Karbalayghareh, M.; Miramirkhani, F.; Eldeeb, Hossıen Badr; Kızılırmak, R. Ç.; Sait, S.Q.; Uysal, Murat (IEEE, 2020-07)Visible light communication (VLC) has been proposed as an alternative or complementary technology to radio frequency vehicular communications. Front and back vehicle lights can serve as wireless transmitters making VLC a ... -
Effect of fog and rain on the performance of vehicular visible light communications
Elamassie, Mohammed; Karbalayghareh, Mehdi; Miramirkhani, Farshad; Kızılırmak, R. Ç.; Uysal, Murat (IEEE, 2018-07-20)In Intelligent Transportation Systems, 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. While VLC ... -
Effect of wiring and cabling topologies on the performance of distributed MIMO OFDM VLC systems
Narmanlıoğlu, Ömer; Kızılırmak, R. Ç.; Miramirkhani, Farshad; Safaraliev, Sadi; Sait, S. M.; Uysal, Murat (IEEE, 2019)Since most indoor spaces have multiple luminaires for illumination, for visible light communication (VLC) systems, multiple-input multiple-output (MIMO) communication emerges as a natural solution to improve the data rates ... -
On the performance of DCO-OFDM visible light communication systems under illumination constraints
Aldırmaz Çolak, S.; Kızılırmak, R. Ç.; Uysal, Murat (IEEE, 2015)In this paper, we consider a DC-biased optical-orthogonal frequency division multiplexing (DCO-OFDM) visible light communication system and investigate its error rate performance under illumination constraints. First, we ... -
On the performance of SC-FDE schemes with decision feedback equalizer for visible light communications
Çelik, Y.; Kızılırmak, R. Ç.; Odabaşıoğlu, N.; Uysal, Murat (IEEE, 2015)In this paper, we investigate the two single carrier frequency domain equalization (SC-FDE) techniques, namely on-off keying single carrier frequency domain equalization (OOK-SC-FDE) and decomposed quadrature optical ... -
Rate-adaptive OFDM MIMO VLC system
Narmanlıoğlu, Ömer; Kızılırmak, R. Ç.; Miramirkhani, Farshad; Uysal, Murat (IEEE, 2018-01-19)In this paper, we investigate link adaptation for an orthogonal frequency division multiplexing (OFDM)-based multiple-input multiple-output (MIMO) visible light communication (VLC) system. The MIMO system under consideration ... -
Relay-assisted OFDM-based visible light communications
Kızılırmak, R. Ç.; Narmanlıoğlu, Ömer; Uysal, Murat (IEEE, 2015-10)In this study, we investigate a relay-assisted visible light communication (VLC) system where an intermediate light source cooperates with the main light source. Specifically, we consider two light sources in an office ... -
SC-FDE based MIMO uplink transmission over infrared communication channels
Narmanlıoğlu, Ömer; Turan, B.; Kızılırmak, R. Ç.; Ergen, S. C.; Uysal, Murat (IEEE, 2018-07-02)In this paper, we propose a multiple-input multiple-output (MIMO) uplink transmission scheme for optical wireless communication applications. The transmission is based on optical single-carrier frequency domain equalization ... -
Single color networks: OFDM-based visible light broadcasting
Kızılırmak, R. Ç.; Uysal, Murat (IEEE, 2015)In this study, we investigate the performance of optical orthogonal frequency division multiplexing (O-OFDM) based visible light broadcasting. Although indoor spaces usually have more than one light source, most of the ... -
Transmit laser selection for underwater visible light communication systems
Elamassie, Mohammed; Al-Nahhal, Mohamed; Kızılırmak, R. Ç.; Uysal, Murat (IEEE, 2019)Visible light communication (VLC) has the potential to serve as a high-speed underwater wireless connectivity solution to support real-time image and video transmission. Underwater propagation medium imposes additional ...
