Channel Modeling for Visible Light Communications
Miramirkhani, Farshad; Uysal, Murat; Panayırcı, Erdal (Springer-Verlag Berlin, 2016)In this chapter, we present a novel and realistic channel modeling approach for visible light communications that overcomes the limitations of previous works. In our work, we consider wavelength dependency, effect of ... -
Comparative Performance Evaluation of VLC, LTE and WLAN Technologies in Indoor Environments
Zeshan, Arooba; Karbalayghareh, Mehdi; Miramirkhani, Farshad; Uysal, Murat; Baykas, Tuncer (IEEE, 2021)Recent years have seen an exponential rise in the demand for indoor wireless connections that have driven future generation networks to aim for higher data rates with extended coverage and affordable rates. The two most ... -

Miramirkhani, Farshad; Narmanlıoğlu, Ömer; Baykas, Tuncer; Uysal, Murat; Panayırcı, Erdal (IEEE-Inst Electrical Electronics Engineers Inc, 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 ... -
A Mobile Channel Model for VLC and Application to Adaptive System Design
Miramirkhani, Farshad; Narmanlıoğlu, Ömer; Uysal, Murat; Panayırcı, Erdal (IEEE-INST Electrical Electronics Engineers Inc, 2017)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 ... -
Modeling of Visible Light Channels and Performance Analysis of ACO-OFDM
Yeşilkaya, Anıl; Alsan, Hüseyin Fuat; Miramirkhani, Farshad; Panayırcı, Erdal; Şenol, Habib; Uysal, Murat (IEEE, 2015)Spectrum scarcity of traditional radio communication has led communication engineers to find new alternatives. Indoor visible light communication is one alternative to solve this problem since its spectrum is not regulated ... -
Novel Channel Models For Visible Light Communications
Miramirkhani, Farshad; Uysal, Murat; Panayırcı, Erdal (Spie-Int Soc Optical Engineering, 2015)In this paper we investigate channel modeling for visible light communications (VLC) using non-sequential ray tracing simulation tools. We create three dimensional realistic simulation environments to depict indoor scenarios ... -
