Channel modeling for visible light communications
Miramirkhani, Farshad; Uysal, Murat; Panayirci, E. (Springer Science+Business Media, 2016)In this chapter, we present a novel and realistic channel modeling approach for visible light communications that overcomes to the limitations of previous works. In our work, we consider wavelength dependency, effect of ... -
Generalized LED index modulation optical OFDM for MIMO visible light communications systems
Başar, E.; Panayirci, E.; Uysal, Murat; Haas, Harald (IEEE, 2016)In this paper, we propose a generalized light emitting diode (LED) index modulation scheme for multiple input multiple output-orthogonal frequency division multiplexing (MIMO-OFDM) visible light communications (VLC) systems. ... -

Uysal, Murat; Miramirkhani, Farshad; Narmanlioglu, Ömer; Baykas, T.; Panayirci, E. (IEEE, 2017)The IEEE has established the standardization group 802.15.7r1 “Short Range Optical Wireless Communications”, which is currently in the process of developing a standard for visible light communication (VLC). As with any ... -
Information theoretical performance analysis and optimisation of cooperative underwater acoustic communication systems
Nouri, Hatef; Uysal, Murat; Panayirci, E. (IEEE, 2016-05)In this study, the authors investigate the information theoretical limits on the performance of single-carrier cooperative underwater acoustic communication systems in the presence of intersymbol interference. The authors ... -
A mobile channel model for vlc and application to adaptive system design
Miramirkhani, Farshad; Narmanlıoğlu, Ömer; Uysal, Murat; Panayirci, E. (IEEE, 2017-05)In this letter, we propose a realistic channel model for visible light communication (VLC) assuming a mobile user. Based on non-sequential ray tracing, we first obtain channel impulse responses for each point over the user ... -
