Cooperative visible light communications
(Springer Science+Business Media, 2016)
In this chapter, we explore the concept of cooperative transmissions in the context of visible light communications (VLC). An indoor office space is considered with two light sources; the one at the ceiling is connected ...
An antenna for implanted device systems
(IEEE, 2017)
In this study, we designed and simulated an embedded spiral-shaped microstrip patch antenna for medical biotelemetry applications. Important design parameters were studied to understand their effect on the antenna performance. ...
Effect of eddy diffusivity ratio on underwater optical scintillation index
(The Optical Society, 2017-10-11)
The performance of underwater optical wireless communication systems is severely affected by the turbulence that occurs due to the fluctuations in the index of refraction. Most previous studies assume a simplifying, yet ...
E shaped antenna surrounded with u shape
(IEEE, 2017)
In this work we designed, simulated, fabricated and measured E-shape microstrip patch antenna. In the process of design, we surrounded E-shape patch antenna with “U” figure. As a result of this work, resonance frequency ...
MIMO-OFDMA tabanlı hücresel ağlarda zamanlayıcıların performans değerlendirmesi
(IEEE, 2017)
Bu bildiride çok-girdili çok-çıktılı (multiple-input multiple-output, MIMO) ve ortogonal frekans bölmeli çoklu erişim (orthogonal frequency division multiple access, OFDMA) tabanlı hücresel kablosuz ağlarda farklı algoritmalara ...
Stochastic resonance in graphene bilayer optical nanoreceivers
(IEEE, 2014-11)
Graphene, a 2-D sheet of carbon atoms, is believed to have diverse application areas ranging from medicine to communications. A novel application is using graphene as a photodetector in optical communications due to its ...
On the performance of NCC-OFDMA systems in the presence of carrier frequency offset
(IEEE, 2017)
Network coded cooperative (NCC) systems have recently gained increasing attention due to their high power and spectral efficiency. For high speed data transmission over frequency-selective channels, NCC is further combined ...
Serration effect on gain for microstrip E-Shape patch antenna
(IEEE, 2016)
In this work we focus on the effect of serration on E-Shape patch antennas. We simulated 2 different E-shape antennas with the same length. The first one has serrated edge and the second one doesn't have. Then we compared ...
Mixed RF and hybrid RF/FSO relaying
(IEEE, 2015)
In this paper, we consider a mixed RF and hybrid RF/FSO system where several mobile users transmit their data over an RF link to a relay node (e.g. a small cell base station) and the relay forwards the information to a ...
Portable low cost ultrasound imaging system
(IEEE, 2016)
The applications of ultrasound in medicine have been increasing in the last decade either in diagnostics or in treatments. Ultrasound is routinely used in clinical examinations, such as pregnancy exams. On the other hand, ...
