Experimental all-optical relay-assisted FSO link with regeneration and forward scheme for ultra-short pulse transmission
(Optical Society of America, 2019)
This paper presents experimental results for an all-optical free-space optical (FSO) relay-assisted system by employing an all-optical regenerate and forward (AORF) scheme in order to increase the transmission link span. ...
Optical Hybrid Fiber/Free-Space and 25 GHz Wireless Transmission using LTE M-QAM Signals
(Instituto de Telecomunicaçoes - Lisboa, 2019)
We experimentally demonstrate a seamless hybrid transmission of radio-over-fiber (RoF), radio-over-free-space optics (RoFSO) and millimeter wave wireless link using long-term evolution (LTE) 4/16/64-QAM signals for broadband ...
Visible light communications: multi-band super-Nyquist CAP modulation
(Optical Society of America, 2019)
In this paper, we experimentally demonstrate the performance of a non-orthogonal multi-band super-Nyquist carrier-less amplitude and phase (m-SCAP) modulation for visible light communications (VLC). We break the orthogonality ...
M-QAM transmission over hybrid microwave photonic links at the K-band
(Optical Society of America, 2019)
Two experimental configurations of a hybrid K-band (25 GHz) microwave photonic link (MPL) are investigated for seamless broadband wireless access networks. Experimental configurations consist of optical fiber, free-space ...
Interference cancellation in MIMO NLOS optical-camera-communication-based intelligent transport systems
(Optical Society of America, 2019)
The ever-increasing number of vehicles on a global level signifies the need for communications between vehicles and the surrounding environment. Visible light communications (VLC) is a viable complementary technology to ...
Mitigation of dispersion and turbulence in a hybrid optical fibre and free-space optics link using electronic equalisation
(German Society for Applied Optics, 2019)
Transmission of a 25 Gbps non-return to zero signal over a hybrid link of 20 km standard single-mode fibre and 500 m free-space optics under weak-to-moderate turbulence regimes is demonstrated via simulation to provide a ...
Experimental analysis of a triple-hop relay-assisted FSO system with turbulence
(Elsevier Science Publishers B.V., 2019)
This paper outlines experimental investigation of the performance of the wireless optical network based on an all-optical triple-hop free space optical (FSO) communications employing amplify-and-forward relaying under the ...
Filter-less WDM for visible light communications using colored pulse amplitude modulation
(Optical Society of America, 2019)
This paper demonstrates, for the first time, a new wavelength-division multiplexing (WDM) scheme for visible light communications using multi-level coloured pulse amplitude modulation (M-CPAM). Unlike traditional WDM, no ...
On Optically Pre-amplified FSO-MISO Non-identical Links with Correlation: Experiment and Analysis
(American Institute of Physics and Magnetic Society of the IEEE, 2019)
In this paper, various link characteristics and bit
error rate (BER) performance of a free-space optical (FSO)
multiple-input-single-output (MISO) system with repetition cod-
ing (RC) is investigated both experimentally ...
Should Analogue Pre-Equalisers be Avoided in VLC Systems?
(IEEE, 2020)
Visible light communication (VLC) systems are highly constrained by the limited 3-dB bandwidth of light-emitting diodes (LEDs). Analogue pre-equalisers have been proposed to extend the LED's bandwidth at the cost of reduced ...
