A low complexity modulation classification algorithm for MIMO systems
(IEEE-INST Electrical Electronics Engineers Inc, 2013-10)
A novel algorithm is proposed for automatic modulation classification in multiple-input multiple-output spatial multiplexing systems, which employs fourth-order cumulants of the estimated transmit signal streams as ...
Blow-up and global existence for a general class of nonlocal nonlinear coupled wave equations
(Academic Press Inc Elsevier Science, 2011-02-01)
We study the initial-value problem for a general class of nonlinear nonlocal coupled wave equations. The problem involves convolution operators with kernel functions whose Fourier transforms are nonnegative. Some well-known ...
Thermoluminescence as a probe in bioactivity studies; the case of 58S sol-gel bioactive glass
(IOP Publishing Ltd, 2011-10-05)
The formation of a carbonated hydroxyapatite (HCAp) layer on the surface of bioactive materials is the main reaction that takes place upon their immersion in physiological fluids. To date, all techniques used for the ...
Cyclostationarity-based robust algorithms for QAM signal identification
(IEEE-INST Electrical Electronics Engineers Inc, 2012-01)
This letter proposes two novel algorithms for the identification of quadrature amplitude modulation (QAM) signals. The cyclostationarity-based features used by these algorithms are robust with respect to timing, phase, and ...
The firing temperature of pottery from ancient Mesopotamia, Turkey, using luminescence methods: a case study for different grain-size fractions
(Wiley-Blackwell, 2014-10)
The assessment of the firing temperature of a prehistoric pottery sample collected from ancient Mesopotamia, Turkey was studied using luminescence techniques. The methods for this estimation involved the observation of the ...
Location and determinants of productivity: The case of the manufacturing industry in Turkey
(M E Sharpe Inc, 2011-11-01)
Discussions in this paper are based on arguments from the geography, economic, and management literatures suggesting that exploring the spatial reasons for productivity in Turkey became significantly important after Turkey ...
An eclectic approach to design tunable amplifiers
(Wiley-Blackwell, 2013-07)
Broadband amplifiers that can accommodate commercial communication standards such as GSM, UMTS, Wi-Fi, and Wi-Max are extremely important for radio equipment manufacturers. To achieve this coverage, the amplifier should ...
Numerical simulation of blow-up solutions for the generalized Davey-Stewartson system
(Taylor & Francis Ltd, 2011-03)
Blow-up solutions for the generalized Davey-Stewartson system are studied numerically by using a split-step Fourier method. The numerical method has spectral-order accuracy in space and first-order accuracy in time. To ...
Some notes on spectra of cographs
(Charles Babbage Res Ctr, 2011-07)
A cograph is a P-4-free graph. We first give a short proof of the fact that 0 (-1) belongs to the spectrum of a connected cograph (with at least two vertices) if and only if it contains duplicate (resp. coduplicate) vertices. ...
Extended reductive perturbation method and its relation to the re-normalization method
(Walter De Gruyter GMBH, 2013-10-25)
In this work, by utilizing the extended reductive perturbation method, we studied the propagation of weakly nonlinear waves in a collisionless cold plasma and formally obtained the governing evolution equations of various ...
