Special issue on broadband mobile communications at very high speeds
(Springer International Publishing Ag, 2012)
[Abstract Not Available]
OFDM with transmit and receive antenna selection based on subcarrier groups
(IEEE, 2012)
In this paper the performance of coded OFDM transmission over multiple antennas is explored when joint transmit and receive antenna selection is employed. The channel is assumed as Rayleigh frequency selective fading channel ...
Capital Markets Trade Openness and Productivity in Emerging Economies Introduction

On the selection of ınterpolation points for rational Krylov Methods
(Springer-Verlag Berlin, 2012)
We suggest a simple and an efficient way of selecting a suitable set of interpolation points for the well-known rational Krylov based model order reduction techniques. To do this some sampling points from the frequency ...
Joint Channel Estimation and Equalization for OFDM based Broadband Communications in Rapidly Varying Mobile Channels
(IEEE, 2010)
This paper is concerned with the challenging and timely problem of channel estimation for orthogonal frequency division multiplexing (OFDM) systems in the presence of frequency selective and very rapidly time varying ...
Fractal Features and Structural Morphological Optical Characteristics of Sol-Gel Derived Silica Nanoparticled Thin Films
(Polish Acad Sciences Inst Physics, 2018)
Nanostructured silica films using a simple and effective sol-gel spin coating technique were synthesized and the influence of ammonia/sol ratios on the particle size and thickness of this film was investigated. In addition ...
The European Union's Immigration Policy: Managing Migration in Turkey and Morocco
(Uluslararası İlişkiler Konseyi Derneği, 2018)
Migration has been an important reason for externalization of the EU’s policies towards non- member third countries. Throughout the 2000s, the European Union has advanced its efforts for externalization of its immigration ...
Phase transitions between different spin-glass phases and between different chaoses in quenched random chiral systems
(Amer Physical Soc., 2017)
The left-right chiral and ferromagnetic-antiferromagnetic double-spin-glass clock model with the crucially even number of states q = 4 and in three dimensions d = 3 has been studied by renormalization-group theory. We find ...
Effects of GNP addition on optical properties and band gap energies of PMMA films
(Wiley, 2019)
In this study the effects of graphene nanoplatelet (GNP) doping on the optical parameters (absorption coefficient alpha and extinction coefficient k) and the optical transition energies (optical band gap and Urbach energies) ...
Energy in Turkey and Russia's Roller-Coaster Relationship
(Seta Foundation, 2017)
Energy relations between Turkey and Russia provide an excellent example of how energy and politics interrelate in countries with a historically up-and-down relationship. Having started in the 1960s the two countries' energy ...
