Outage performance of multi-hop hybrid FSO/RF communication systems
(IEEE, 2015)
In this paper, five scenarios are considered for the realization of a multi-hop hybrid free-space optical/radio frequency (FSO/RF) communication system with decode-and-forward (DF) relaying, and analytical outage probability ...
Non-orthogonal multiple access (NOMA) for indoor visible light communications
(IEEE, 2015)
Providing multiple access support to visible light communication (VLC) systems requires new networking architecture. Non-orthogonal multiple access (NOMA) is a proposed multiple access technique for future cellular systems. ...
Performance evaluation of LOS and NLOS vertical inhomogeneous links in underwater visible light communications
(IEEE, 2018-03-22)
In this paper, underwater visible light communication (UWVLC) vertical links are modeled and evaluated, taking account of the inhomogeneous nature of underwater (UW) environment. An equivalent simplified model of stratified ...
Spectrum trading for non-identical channel allocation in cognitive radio networks
(IEEE, 2013)
In this paper, we investigate spectrum trading via auction approach for exclusive usage spectrum access model in cognitive radio networks. We consider a realistic valuation function which depends on channel capacity, delay ...
Finite-SNR DMT analysis for multisource multirelay NCC systems with imperfect CSI
(IEEE, 2016)
Network coded cooperative (NCC) systems have recently attracted attention with their high spectral and power efficiency. In this paper, we investigate the information theoretical limits of NCC systems in the presence of ...
An adaptive modulation scheme for coded free-space optical systems
(IEEE, 2014)
For very slowly-varying fading channels as in the case of atmospheric turbulence-induced fading, it is possible to reliably estimate the channel state information and send it back to the transmitter. The transmitter can ...
Cooperative visible light communications with full-duplex relaying
(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 ...
Unmanned-aerial-vehicle-assisted cooperative communications for visible light communications-based vehicular networks
(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 ...
VLC ağları için genetik algoritma temelli kaynak atama tekniği
(IEEE, 2017)
Bu çalışmada, görünür ışıkla haberleşme (VLC) ağları için genetik algoritma (GA) temelli kaynak atama tekniği önerilmiştir. Optik VLC agı mevcut aydınlatma altyapısının kullanıldığı iç mekanlarda çok küçük boyutlu hücrelerden ...
Relay-assisted OFDM-based visible light communications
(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 ...
