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 ...
Which anesthetic agent alters the hemodynamic status during pediatric catheterization? Comparison of propofol versus ketamine
(W.B. Saunders Co Ltd, 2003)
Objective: To compare the effects of propofol and ketamine on systemic and pulmonary circulations in pediatric patients scheduled for elective cardiac catheterization. Design: Prospective randomized and blinded. Setting: ...
Corneal ring segments (INTACS) for the treatment of asymmetrical astigmatism of the keratoconus. Follow-up after 2 years
(Masson Editeur, 2003)
Objective: To evaluate the use of corneal ring segments (INTACS) for the treatment of asymmetrical astigmatism in keratoconus. Material and methods: This prospective study involved nine eyes of seven patients who were ...
Unconditional maximum likelihood approach for localization of near-field sources in 3-D space
(IEEE, 2004)
Since maximum likelihood (ML) approaches have better resolution performance than the conventional localization methods in the presence of less number and highly correlated source signal samples and low signal to noise ...
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 ...
The role of posterior pericardiotomy on the incidence of atrial fibrillation after coronary revascularization
(Edizioni Minerva Medica, 2003)
Aim. Pericardial effusion and atrial fibrillation (AF) are two common complications in coronary revascularization surgery. The aim of this study was to evaluate the efficiency of posterior pericardiotomy in pericardial. ...
