Pilot Symbol Aided Channel Estimation for Spatial Modulation-OFDM Systems and its Performance Analysis with Different Types of Interpolations
(Springer, 2017)
Spatial modulation orthogonal frequency division multiplexing (SM-OFDM) system has been recently proposed as an alternative for multiple-input multiple-output (MIMO)-OFDM systems to increase spectral efficiency by keeping ...
Reflection Modeling Based Broadband Matching Network Design
(Walter De Gruyter, 2017)
In this paper a new broadband matching network design approach based on reflection modeling is proposed which has two parts: impedance data generation and modeling. In the approach firstly the output impedance data of the ...
A Mobile Channel Model for VLC and Application to Adaptive System Design
(IEEE-INST Electrical Electronics Engineers Inc, 2017)
In this letter we propose a realistic channel model for visible light communication (VLC) assuming a mobile user. Based on non-sequential ray tracing we first obtain channel impulse responses for each point over the user ...
Turkey and the changing energy geopolitics of Eurasia
(Elsevier Science, 2019)
While Turkeys geographical location is usually viewed as a major advantage in the energy sphere since many countries in its immediate neighbourhood require active Turkish collaboration in order to export or import oil and ...
Broadband Matching via Unequal Length Cascaded Transmission Lines
(World Scientific Publ Co Pte Ltd, 2017)
In this paper a new approach based on the real frequency technique (RFT) has been proposed to solve broadband matching problems using cascaded unequal length transmission lines. At the end of the design process optimum ...
Two-layer earth structure parameter estimation and seasonal analysis
(IEEE, 2018)
The determination of soil parameters is an important topic regarding the safe and efficient design of electrical grounding systems as well as the accurate calculation of the per-unit-length parameters of overhead transmission ...
Importance of Regional Differences in Brain Throughout Aging for Down Syndrome
(Association for Computing Machinery, 2018)
Down syndrome (DS) which affects approximately one in 700 live births is caused by an extra copy of the long arm of human chromosome 21 (HSA21). Statistical analysis has been done for understanding the protein expression ...
Improvement of indoor positioning accuracy of ultra-wide band sensors by using big bang-big crunch optimization method
(Pamukkale Univ, 2018)
Ultra-wide Band technology is an emerging technology that offers successful solutions in many indoor positioning systems and performs better than other methods. In this study an indoor positioning system using Ultra-wide ...
Greek Foreign Policy in Defence of the National Interest: Teetering between Exceptionalism and Integration
(Uluslararası İlişkiler Konseyi Derneği, 2018)
This paper aims to explain how crisis-ridden Greece defines and defends its national interest. The constellation of the twin economic and migration crises coupled with the increasingly transactional nature of the global ...
An Improved Adaptive Subspace Tracking Algorithm Based on Approximated Power Iteration
(IEEE-INST Electrical Electronics Engineers Inc, 2018)
A subspace tracking technique has drawn a lot of attentions due to its wide applications. The main objective of this approach is to estimate signal or noise subspace basis for the sample covariance matrix. In this paper ...
