Design and implementation of a quad element patch antenna at 5.8 GHz
(The Applied Computational Electromagnetics Society, 2018-10)
This paper presents simulation and experimental verification of a quad microstrip patch antenna that operates at 5.8 GHz. Sonnet antenna design software was used to simulate the performance of the antenna. To reduce the ...
A simulation study of cooperative underwater acoustic communication
(2012-08)
Cooperative communication promises significant performance gains in terms of link reliability, spectral efficiency, system capacity, and transmission range. Due to its indisputable advantages for high-speed underwater ...
Multi-pick round robin arbiter
(2012-08)
In this thesis, we propose two multi(m)-pick Round Robin Arbiter (RRA) architectures. An m-pick RRA selects the m topmost requests out of n inputs with priority order indicated by an internally kept pointer (with an update ...
Design and comparison of 4 types of dual resonance proximity coupled microstrip patch antennas
(The Applied Computational Electromagnetics Society, 2018-10)
In this paper there are four different shapes of proximity patch antennas (straight, trimmed, trapezoid and ribbon). The minimum input match achieved with the straight proximity patch antenna as -39.68 dB. The maximum gain ...
Space-track modulation and coding for high density aerial vehicle downlink networks with free space optical and visible light communications
(TÜBİTAK, 2019)
Aerial vehicles (AVs) have challenges in terms of realizing low complexity and wide coverage area wireless communications architectures, especially for crowded or high density groups of AVs with state-of-the-art free space ...
Experimental QOS-based comparison of olsr and B.A.T.M.A.N. mesh routing algorithms for multimedia home networks
(2013-08)
Wireless Mesh Networks (WMNs) allow communication of two nodes via a multi-hop route, without the need for an infrastructure such as base stations. Routing has been a fundamental issue for this type of communication networks. ...
Analog clock tree synthesis
(2014-01)
Anahtarlamalı analog devrelerin (AAD) saat ağı tasarımı ciddi zaman gerektiren ve yongaların tekrar elden geçirilmesine sebep olabilecek hatalara açık, elle yapılan bir işlemdir. Bu probleme otomatik ya da yarı-otomatik ...
Combined aes + aegis architectures for high performance and lightweight security applications
(2014-08)
Günümüzde kriptografi banka kartlarından telefonlara, arabalardan haberleşme araçlarına ve bulut hizmetlerine kadar pek çok alana girdi. Digital bilgiyi yetkilendirilmemiş erişimlere karşı korumak için bir çok şifreleme ...
Resource allocation for visible light communication systems using simulated annealing based on a problem-specific neighbor function
(IEEE, 2019)
In this paper, we consider a visible light communication (VLC) system with direct current-biased orthogonal frequency division multiplexing (DC-OFDM) and investigate resource allocation for a multi-user environment. Based ...
Application-based scheduling for indoor femtocell networks
(2013-01)
This thesis is concerned with designing a QoS-enabled, application-based scheduler for indoor femtocell networks. For this purpose, a novel scheduler is proposed which takes into account the quality of service (QoS) ...
