Cooperative inter-vehicular communications in highway traffic
(2011)
In this paper, we investigate the performance of a single relay assisted cooperative vehicular network in a highway traffic scenario. Source and relaying vehicles are assumed to be traveling in the same direction with ...
All-optical amplify-and-forward relaying system for atmospheric channels
(IEEE, 2012-10)
In this letter, we investigate the performance of a dual-hop free space optical link with an all-optical amplify-and-forward relay. We employ photon counting methodology and derive closed form expressions for the end-to-end ...
Optimal relay placement in cooperative free-space optical communication systems
(IEEE, 2012)
Relay-assisted free-space optical (FSO) transmission exploits the fact that atmospheric turbulence fading variance is distance dependent and yields significant performance gains by taking advantage of the resulting shorter ...
SC-FDE based MIMO uplink transmission over infrared communication channels
(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 ...
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 ...
Adaptive power loading for multi-relay OFDM regenerative networks with relay selection
(IEEE, 2012-03)
In this paper, we propose an adaptive power loading algorithm for an OFDM (orthogonal frequency division multiplexing)-based multi-relay regenerative network with relay selection. The proposed scheme is based on selecting ...
Relay selection in dual-hop vehicular networks
(IEEE, 2011-02)
In this letter, we investigate cooperative diversity with relay selection over cascaded Rayleigh fading channels. In particular, we analyze the performance of a relay selection scheme for cooperative vehicular networks ...
Adaptive bit loading for multi-relay cooperative orthogonal frequency division multiple with imperfect channel estimation
(IEEE, 2012-08-14)
In this study, the authors introduce an adaptive bit loading scheme for an amplify-and-forward orthogonal frequency division multiple cooperative system with relay selection. The proposed bit loading scheme maximises the ...
Performance analysis of MIMO free-space optical communication systems with selection combining
(IEEE, 2013)
In this paper, we investigate the outage performance of a multi-input multi-output (MIMO) free-space optical (FSO) communication system with selection combining (SC). Under the assumption of log-normal distributed atmospheric ...
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 ...
