On channel estimation in DC biased optical OFDM systems over VLC channels
(Ieee, 2016)
Visible Light Communication(VLC) has been considered as a potential access option for 5G wireless systems to solve performance limitation due to bandwidth shortage at radio frequency (RF) band. in (VLC) system, illumination ...
Spline interpolation based channel estimation for ACO-OFDM over visible light channels
(Ieee, 2016)
Visible light communication has been considered one of promising candidate technology to solve performance limitation due to bandwidth shortage at radio frequency (RF) band. in VLC system, the visible light is used not ...
Particle swarm optimization algorithm based decision feedback equalizer for underwater acoustic communication
(Ieee, 2016)
In this paper, we proposed particle swarm optimization (PSO) algorithm based adaptive decision feedback equalizer (DFE) for underwater acoustic communication (UWAC). in the literature, although ocean ambient noise is ...
Impact on efficiency of core materials in dry type transformers
(Ieee, 2016)
Transformers have an important place in electric transmission and distribution systems. Transmission and distribution efficiency of transformers should be high in regard to energy efficiency. Efficiency is one of important ...
Pilot assisted channel estimation for asymmetrically clipped optical OFDM over visible light channels
(Ieee, 2016)

Investigation of thermoelectric cooler system effect on induction motor performance
(Institute of Electrical and Electronics Engineers Inc., 2021)
Induction motors are generally cooled by the fan connected to the motor shaft, as the cooling of electrical machines is important. In this study, an alternative method is proposed for cooling of induction motors. Thermoelectric ...
Strain-engineered SiGe nanomembrane quantum-well infrared photodetectors
(Ieee, 2017)
SiGe quantum-well nanomembranes, where stress from lattice mismatch is relaxed via elastic strain sharing rather than defect formation, are used to develop intersubband photodetectors showing improved performance compared ...
III-nitride terahertz photodetectors for the reststrahlen gap of intersubband optoelectronics
(Spie-Int Soc Optical Engineering, 2017)
We report the development of terahertz intersubband photodetectors based on GaN/AlGaN quantum wells, covering the frequency range that is fundamentally inaccessible to existing III-V semiconductor devices due to Reststrahlen ...
Remote leak hole localization for underwater natural gas pipelines
(Ieee, 2017)
A vast amount of natural gas pipelines are installed underwater and they can be punctured because of various reasons such as corrosion and their increasing ages. in this study, nature of acoustic signals which are generated ...
