A custom-design atmospheric channel emulator for the performance evaluation of free space optical communication systems
(IEEE, 2017)
In this paper, we present our custom design atmospheric channel emulator for free space optical (FSO) system evaluations in a controlled environment. Our emulator is in the form of an atmospheric chamber with dimensions ...
Coagulation measurement from whole blood using vibrating optical fiber in a disposable cartridge
(SPIE, 2017-11)
In clinics, blood coagulation time measurements are performed using mechanical measurements with blood plasma. Such measurements are challenging to do in a lab-on-a-chip (LoC) system using a small volume of whole blood. ...
CSSTag: optical nanoscale radar and particle tracking for in-body and microfluidic systems with vibrating graphene and resonance energy transfer
(IEEE, 2017-12)
Biological particle tracking systems monitor cellular processes or particle behaviors with the great accuracy. The emissions of fluorescent molecules or direct images of particles are captured with cameras or photodetectors. ...
RImCom: raster-order image compressor for embedded video applications
(Springer International Publishing, 2017)
This paper presents a real-time, rate controlled, end-to-end (encoder and decoder) hardware solution for memory compression of raster-order video streams—named RImCom (short for Raster-order Image Compression). RImCom ...
On the effects of temperature on the performances of FSO transmission under qatar's climate
(IEEE, 2017-11-14)
Strong atmospheric turbulence can highly affect the free space optical (FSO) link. In fact, the strength of turbulence is depending on weather factors where the temperature is considered as the main parameter increasing ...
Link adaptation for MIMO OFDM visible light communication systems
(IEEE, 2017-11-10)
In this paper, we investigate link adaptation for an orthogonal frequency division multiplexing (OFDM)-based multiple-input multiple-output (MIMO) visible light communication (VLC) system. The proposed adaptive OFDM VLC ...
Dual-band gemini-shaped microstrip patch antenna for C-band and X-band applications
(IEEE, 2017)
In this paper, a novel single-layer Gemini-shaped patch antenna with dual-band characteristics is presented. The proposed patch antenna, with design operating frequencies of 6.53 GHz and 8.62 GHz, is targeted for applications ...
Rectangular slotted square patch antenna with a floating ring
(IEEE, 2017)
In this paper, a rectangular slotted square patch antenna with a floating ring and single point feed is presented. The proposed patch antenna, when optimized, achieved the highest gain of 7.17 dB at 7.12 GHz with -6.97 dB ...
Performance of multicarrier cooperative communication systems over underwater acoustic channels
(IET Communications, 2017)
Multicarrier transmission in the form of orthogonal frequency division multiplexing (OFDM) is an efficient method to handle inter-symbol interference resulting from the frequency selectivity of the underwater acoustic (UWA) ...
Optical MIMO-OFDM with generalized LED index modulation
(IEEE, 2017-08)
Visible light communications (VLC) is a promising and uncharted new technology for the next generation of wireless communication systems. This paper proposes a novel generalized light emitting diode (LED) index modulation ...
