DMT analysis of multi-hop coherent FSO communication over atmospheric channels
(IEEE, 2011)In this paper, we investigate the diversity-multiplexing tradeoff (DMT) of a multi-hop coherent free-space optical (FSO) system over atmospheric channels. We consider a relay-assisted FSO system with decode-and-forward ... -
Effect of LED wiring and cabling topologies on visible light communication channels
(IEEE, 2018-01-19)Visible light communication (VLC) is an emerging short-range wireless access technology. It involves the dual use of illumination infrastructure for communication purposes and builds upon the principle of modulating light ... -
Generalized LED index modulation optical OFDM for MIMO visible light communications systems
(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. ... -
The impact of location errors on achievable rates in OFDM-based multi-user visible light communication systems
(IEEE, 2014)Visible light communication (VLC) is a communication technology in which data is transferred by modulating the visible light intensity. VLC signals degrade significantly due to the absence of the line of sight (LOS) between ... -
Optimal combiners in optical wireless systems with spatial diversity and pre-amplification
(IEEE, 2016)We present analytical results on the operation of a pre-amplified optical wireless communication (OWC) system that also takes advantage of spatial diversity to improve its outage probability and average bit-error-rate (BER) ... -
Performance evaluation of multiple-bit delay detection with majority vote decision rule in optical DPSK systems
(IEEE, 2011)In this paper, the performance of multiple-bit delay detection (MBDD) systems in optical differential phase shift keying (DPSK) is investigated. Assuming that the dominant noise in the system is originated by the optical ... -
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 ... -
Survey on free space optical communication: a communication theory perspective
(IEEE, 2014)Optical wireless communication (OWC) refers to transmission in unguided propagation media through the use of optical carriers, i.e., visible, infrared (IR), and ultraviolet (UV) bands. In this survey, we focus on outdoor ...
