Nvis Hf Signal Propagation In Ionosphere Using Calculus Of Variations
(2019)
Modeling Near Vertical Incidence Sounding (NVIS) High Frequency (HF) signal propagation in the ionosphere is important. Because, ionosondes which are special types of radars probing the ionosphere with certain HF frequencies ...
Optimal Joint Modulation Classification And Symbol Decoding
(2019)
In this paper, modulation classification and symbol decoding problems are jointly considered and optimal strategies are proposed under various settings. In the considered framework, there exist a number of candidate ...
Examination Of Formal Thought Disorder And Its Clinical Correlates With The Turkish Version Of The Thought And Language Disorder Scale (Tald-Tr) In Schizophrenia
(2019)
Background: Formal thought disorder (FTD) is considered to be a fundamental feature of schizophrenia. This study aims to analyze psychometric properties of the Turkish version of “Thought and Language Disorder Scale (TALD)” ...
State-Space Identification Of Switching Linear Discrete Time-Periodic Systems With Known Scheduling Signals
(2019)
In this paper, we propose a novel frequency domain state-space identification method for switching linear discrete time-periodic (LDTP) systems with known scheduling signals. The state-space identification problem of linear ...
Application Of Equivalent Paraboloid Antenna And Equivalent Feed Methods For Off-Focus Fed Dual Asymmetric Reflectors
(2019)
Off-focus fed reflector antennas are preferred to prevent loss due to aperture blockage effect of secondary reflector and feed in the reflector antenna system. For this reason, it is important to calculate the radiation ...
Application Of The Shifted Frequency Internal Equivalence To Two Dimensional Lossy Objects
(2019)
Performance of a new method, Shifted Frequency Internal Equivalence (SFIE) is studied in the analysis of scattering from two dimensional lossy objects. This method finds the solution of a wideband scattering problem faster ...
Characterization Of Transmission And Reflection Of Ku-Band Split Ring Resonator Reflectarray Using Waveguide Method
(2019)
The analysis, design, and measurement of a split ring resonator (SRR) reflectarray are presented. The 6 different designs of a 2 x 4 reflectarray are simulated to analyze the effect of split's positions on the resonance ...
Lonolab-Map: An Automatic Spatial Interpolation Algorithm for Total Electron Content
(Tubitak Scientific & Technical Research Council Turkey, 2018)
Investigation of the variability of total electron content (TEC) is one of the most important parameters of the observation and monitoring of space weather, which is the main cause of signal disturbance in space-based ...
A New Algorithm for High-Quality Ionogram Generation and Analysis
(Amer Geophysical Union, 2002)
Standard digital ionograms that are generated by fast Fourier transform or autoregressive modeling suffer from high interference levels due to other users of the HF channel which produce artifacts and distortion, hence ...
Spatio-Temporal Interpolation Of Total Electron Content Using A Gps Network
(Amer Geophysical Union, 2013)
Constant monitoring and prediction of Space Weather events require investigation of the variability of total electron content (TEC), which is an observable feature of ionosphere using dual-frequency GPS receivers. Due to ...
