Detection of interdependent primary systems using wideband cognitive radios
(Elsevier GMBH Urban & Fischer Verlag, 2013)
Cognitive radios (CRs) may be sharing multiple frequency bands with primary systems if the CR is a wideband or an ultra wideband (UWB) system. In that case the CR should ensure all the coexisting primary systems in these ...
MP-SAGE Based Channel Estimation for Underwater Cooperative OFDM Systems
(IEEE, 2013)
In this paper an efficient channel estimation algorithm is proposed for amplify-and-forward (AF) cooperative relay based orthogonal frequency division multiplexing (OFDM) system in the presence of sparse underwater acoustic ...
A New Technique for OFDM: OFDM-Index Modulation
(IEEE, 2013)
In this study a novel scheme called orthogonal frequency division multiplexing with index modulation (OFDMIM) is proposed for frequency selective channels. In this scheme the information is conveyed not only by only M -ary ...
Action Recognition Using Random Forest Prediction with Combined Pose-based and Motion-based Features
(IEEE, 2013)
In this paper we propose a novel human action recognition system that uses random forest prediction with statistically combined pose-based and motion-based features. Given a set of training and test image sequences (videos) ...
Primary User Detection in IEEE 802.15.4a Based Wireless Sensor Networks
(IEEE, 2013)
Ultra wideband impulse radio (UWB-IR) technology has been defined in the IEEE 802.15.4a standard for location and ranging applications. In this paper UWB-IR sensors are considered in wireless sensor networks (WSNs) with ...
Big Data Platform Development with a Domain Specific Language for Telecom Industries
(IEEE, 2013)
This paper introduces a system that offer a special big data analysis platform with Domain Specific Language for telecom industries. This platform has three main parts that suggests a new kind of domain specific system for ...
Foster impedance data modeling via singly terminated LC ladder networks
(TUBITAK Scientific & Technical Research Council Turkey, 2013)
In this work a lossless model is developed for the given Foster impedance data. In the model a 2-port short-or open-terminated LC ladder is used. After applying the proposed algorithm a realizable driving-point reactance ...
The great game in the Levant: energy geopolitics in the Eastern Mediterranean [Levant’ta büyük oyun: Doğu Akdeniz’in enerji jeopolitiği]
(Uluslararası İlişkiler Konseyi Derneği, 2012)
This study explores the historical evolution of the Levant region from the trade system to hydrocarbon geopolitics by using a longue duree approach one which evaluates the region's present situation in light of developments ...
An evolutionary approach for tuning parametric Esau and Williams heuristics
(Palgrave Macmillan Ltd., 2012)
Owing to its inherent difficulty many heuristic solution methods have been proposed for the capacitated minimum spanning tree problem. On the basis of recent developments it is clear that the best metaheuristic implementations ...
Temperature effect on the swelling of PAAm-kappa-carrageenan composites
(Wiley-Blackwell, 2012)
The steady-state fluorescence (SSF) technique was used for studying swelling of disc-shaped polyacrylamide (PAAm)-kappa-carrageenan (kappa C) composites which were prepared by free-radical crosslinking copolymerization at ...
