Multi-hop quantum key distribution with passive relays over underwater turbulence channels
(IEEE, 2020)
Absorption, scattering, and turbulence experienced in underwater channels severely limit the range of quantum communications. In this paper, to overcome range limitations, we investigate a multi-hop underwater quantum key ...
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 ...
A 1GS/s, 9-bits DAC interleaved (2+1)-bit then 2-bit per cycle SAR ADC
(Istanbul University, 2020-07)
This paper presents a high speed Successive Approximation Register Analog to Digital Converter (SAR ADC) for low-noise low-power satellite transceiver applications. The system is a (2+1) then 2-bit per cycle SAR ADC of ...
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 ...
Crucial topics in computer architecture education and a survey of textbooks and papers
(International Association of Engineers, 2020)
We have been teaching undergraduate computer architecture since 2012 in an unconventional way. Most undergraduate computer architecture courses are based on microprocessors, and they quickly move into advanced topics such ...
Preparation and characterization of freely-suspended graphene nanomechanical membrane devices with quantum dots for point-of-care applications
(MDPI, 2020-01-01)
We demonstrate freely suspended graphene-based nanomechanical membranes (NMMs) as acoustic sensors in the audible frequency range. Simple and low-cost procedures are used to fabricate NMMs with various thicknesses based ...
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 ...
