Detection of interdependent multiband systems for cognitive radios and ultra-wideband systems
(Kadir Has Üniversitesi, 2012)
As a result of advances in the wireless technology new systems have been proposed and hence more frequency bands are occupied in the spectrum. Therefore the number ofavailable frequency bands for future wireless communication ...
Phase noise estimation for wireless communication systems
(Kadir Has Üniversitesi, 2011)
in wireless communication systems information symbols are transmitted through a communication channel which are affected many degradation factors. Besides fading and multipath effect of channel transmitted symbols are ...
Femtocell design for data communications in mobile networks
(Kadir Has Üniversitesi, 2013)
in this thesis game theoretic utility-based adaptive power control algorithm for uplink of femtocell networks is performed for mitigation of interference in two different ways. The first one is allocation of femtocell ...
Log analysis with anomaly detection
(Kadir Has Üniversitesi, 2019)
Detection of anomalies in the data is an important data analysis job for server logs as they will reveal many benefits. Different types of methods can be used for anomaly detection: supervised, semi-supervised, and supervised ...
Primary user detection in Ultrawide-band based wireless sensor networks
(Kadir Has Üniversitesi, 2013)
in this thesis ultra-wideband (UWB) based wireless sensor networks (WSNs) are considered for the detection of a primary user. Different from earlier works (i) both uplink and downlink information of the primary user are ...
Bayesian learning for cellular neural networks
(Kadir Has Üniversitesi, 2013)
Cellular Neural Networks have been an active research eld since their introduction in the late 80s. Several training algorithms are proposed since then. All have their advantages and disadvantages. Most of them uses ...
Modelling of visible light channels and performance analysis for optical ofdm systems
(Kadir Has Üniversitesi, 2016)
This work is concerned with a challenging problem of modeling and simulation of visible light communications (VLC) channels for optical wireless communication (OWC) systems. A proper channel model for VLC is absent in the ...
Performance of ieee 802.11af systems under realistic channel conditions
(Kadir Has Üniversitesi, 2016)
As the analog TV broadcasting channels have become less frequently used in the last decade there has been a great interest in these frequency bands for the deployment of regional local and personal area networks. Among ...
Scattering transfer matrix factorization based synthesis of resistively terminated LC ladder networks
(Kadir Has Üniversitesi, 2011)
Bu yüksek lisans tezimde, direnç ile sonlandırılmış LC merdiven devrelerin sentezi için algoritmalr önerilmiştir. Bu algoritmalar saçılma transfer matrisi faktorizasyonuna dayanır. Alçak-geçiren, yüksek-geçiren, band-geçiren ...
Explicit solutions of two-variable scattering equations and broadband matching network design
(Kadir Has Üniversitesi, 2019)
Karışık devre elemanı (toplu ve dağıtılmış eleman) içeren devreler mikrodalga mühendisliği için önemli bir konudur (Aksen, 1994). Toplu elemanlar arasındaki bağlantılar, iletim hattı olarak düşünülüp devre elemanı olarak ...
