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 ...
Precise Measuring Test Bed for Characterization of Mode Field Distribution in Different types of Multimode Fibers
(Zeithamlová Milena Ing. - Agentura Action M, 2019)
In this paper we present experimental results from
precise measurements of mode field distribution in various
commercial multimode (MM) fiber types. We characterize the
mode field distribution by the encircled flux (EF) ...
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. ...
Efficient Exploitation of Radio Frequency and Visible Light Communication Bands for D2D in Mobile Networks
(IEEE, 2019)
The concept of device-to-device (D2D) communication, combining common radio frequency (RF) and visible light communication (VLC), is seen as a feasible way how to cope with spectrum crunch in the RF domain and how to ...
Statistical channel modelling of dynamic vehicular visible light communication system
(Elsevier, 2021)
This paper studies a statistical channel model for dynamic vehicular visible light communication systems. The proposed model considers the effect of variation in inter-vehicular spacing and the geometrical changes on path ...
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 ...
Exact modeling of photonic crystal fibers for determination of fundamental properties
(ELSEVIER SCIENCE INC, 2020)
We present a simple but highly accurate modeling technique for real photonic crystal fibers (PCFs) characterization. We determine the influence caused by idealized model parameters. Our technique can be applied to arbitrary ...
Experimental validation of indoor relay-assisted visible light communications for a last-meter access network
(Elsevier, 2019)
This paper provides experimental results for a relay-assisted visible light communications (VLC) link usinga white light-emitting diode (LED) for a last-meter access network. We demonstrate that a relay-based VLCscheme ...
Impact of Channel Correlation on Different Performance Metrics of OSSK-Based FSO Systems
(Institute of Electrical and Electronics Engineers, 2020)
In this paper, we study the impact of correlation on the bit error rate (BER) and the channel capacity of a free-space optical (FSO) multiple-input-multiple-output (MIMO) system employing optical space shift keying (OSSK) ...
Seamless 25 GHz Transmission of LTE 4/16/64-QAM Signals Over Hybrid SMF/FSO and Wireless Link
(IEEE LEOS JLT Editorial Office, 2019)
We propose and experimentally demonstrate a photonics-assisted converged radio-over-fiber (RoF), radio-over-free-space optics (RoFSO) and millimeter-wave (MMW) wireless transmission system for use in broadband wireless ...
