Markov-based performance analysis of medium access in visible light communications
(IEEE, 2015)
Visible light communication (VLC) uses the illumination infrastructure to provide high speed wireless connectivity. VLC has recently emerged as a promising alternative/complementary technology to conventional radio-frequency ...
Outage analysis of q-duplex RF/FSO relaying
(IEEE, 2015)
In this paper, we propose and analyze a novel q-duplex radio frequency/free space optical (RF/FSO) relaying protocol for a mixed RF and hybrid RF/FSO communication system. In our scheme, several mobile users transmit their ...
Single color networks: OFDM-based visible light broadcasting
(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 ...
Görünür ışık kanalların modellenmesi ve ACO-OFDM için başarım analizi
(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 ...
Fast-decodable MIMO HARQ systems
(IEEE, 2015-05)
This paper presents a comprehensive study on the problem of decoding complexity in a Multi-Input Multi-Output (MIMO) Hybrid Automatic Repeat reQuest (HARQ) system based on Space-Time Block Codes (STBCs). We show that there ...
Performance of multiuser scheduling in free space optical systems over atmospheric turbulence channels
(IEEE, 2015-10)
In this study, the authors consider a multiuser multiple-input multiple-output (MU-MIMO) free space optical (FSO) communication system and investigate the performance of various scheduling protocols which provide different ...
Relay-assisted OFDM-based visible light communications over multipath channels
(IEEE, 2015-07)
In this paper, we investigate the performance of relay-assisted visible light communication (VLC) system over multipath channels. We consider an indoor environment where the ceiling light serves as the information source ...
On the performance of MIMO FSO communications over double generalized gamma fading channels
(IEEE, 2015)
A major performance degrading factor in free space optical communication (FSO) systems is atmospheric turbulence. Spatial diversity techniques provide a promising approach to mitigate turbulence-induced fading. In this ...
Novel channel models for visible light communications
(SPIE, 2015-02-07)
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 ...
On the performance of DCO-OFDM visible light communication systems under illumination constraints
(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 ...
