Channel modelling for light communications: Validation of ray tracing by measurements
(IEEE, 2020)
Light communications, also denoted as LiFi, is promising for future wireless indoor networks. For performance evaluation, the IEEE P802.15.13 and P802.11bb standardization groups agreed upon channel models based on ...
A flexible OLED VLC system for an office environment
(IEEE, 2020)
The potential use of flexible substrate-based organic light emitting diodes (OLEDs) as curved or rolled lighting sources offers news opportunities for the implementation of visible light communications (VLC) in indoor ...
Low-cost thin-film passive RFID circuits and detector system
(Cambridge University Press, 2020-06)
This paper discusses the design of chip-less RFID tags of a standard pocket size of 69 mm by 156 mm. These tags are based on lumped elements of copper metal traces constructed on a thin polyamide flexible substrate. Moreover, ...
Resonance-filtering combo system for continuous wireless charging range coverage
(Cambridge University Press, 2020-09)
Distribution of wireless power charging field uniformly on a large area pad is critical for power receivers, particularly for wearable devices, wherein small form factor coils are involved. Since the receiver coil size is ...
Semi- and fully-random access LUTs for smooth functions
(Springer, 2020)
Look-Up Table (LUT) implementation of complicated functions often offers lower latency compared to algebraic implementations at the expense of significant area penalty. If the function is smooth, MultiPartite table method ...
Experimental evaluation of a software defined visible light communication system
(IEEE, 2020)
Visible light communication (VLC) allows the dual use of light-emitting diodes (LEDs) for illumination and communication purposes. With its large bandwidth and immunity to electromagnetic interference, VLC can be used as ...
Multi-hop quantum key distribution with passive relays over underwater turbulence channels
(The Optical Society, 2020-12-01)
Absorption, scattering, and turbulence experienced in underwater channels severely limit the range of quantum communication links. In this paper, as a potential solution to overcome range limitations, we investigate a ...
Live multicast video streaming from drones: an experimental study
(Springer Nature, 2020-01-01)
We present and evaluate a multicast framework for point-to-multipoint and multipoint-to-point-to-multipoint video streaming that is applicable if both source and receiver nodes are mobile. Receiver nodes can join a multicast ...
Photon statistics effects on a QRNG of vacuum fluctuations
(Optica Publishing Group, 2020-09-14)
Optical scattering enhances randomness characteristics, increases the chaotic behavior of coherent sources, broadens the distribution of photon statistics and makes it super-Poissonian which allows faster sampling compared ...
Down-conversion emission profile characterisation via camera
(Optica Publishing Group, 2020-12-14)
We present a method to improve the brightness and collection efficiency of the spontaneous parametric down-conversion source by monitoring the mode shape using camera and correcting it with collection optics.
