On the effects of random timing jitter on spectrum sensing algorithms based on cyclostationarity
(IEEE, 2009)
Cognitive radio is an enabling technology, which is expected to lead to a more efficient utilization of the available spectral resources due to its flexibility and its ability to sense its spectral environment. Recently, ...
Nonlinear waves in a stenosed elastic tube filled with viscous fluid: Forced perturbed korteweg-de vries equation
(Springer Science and Business Media, LLC, 2008)
In the present work, treating the artery as a prestressed thin-walled and long circularly cylindrical elastic tube with a mild symmetrical stenosis and the blood as an incompressible Newtonian fluid, we have studied the ...
A novel method to represent the speech signals by using language and speaker independent predefined functions sets
(IEEE, 2004)
In this paper a new modeling method of speech signals is introduced. The proposed method is based on the generation of the so-called Predefined Signature S={s(R)(t)} and Envelope Function E = {e(K)(t)} Sets (PSEFS). These ...
Tel file geometrilerinin sıradüzensel küme bölüntüleme ile spektral kodlaması
(IEEE, 2007-09-04)
Çalışmamızda bir dönüşümle elde edilen spektral katsayılar kullanılarak betimlenen tel file geometri bilgisi, katsayılara bütün bit düzlemlerinde en doğru öncelikler atanarak sıradüzensel bir küme bölüntüleme algoritmasıyla ...
Force-directed approaches to sensor localization
(SIAM, 2006)
We consider the centralized, anchor-free sensor localization problem. We consider the case where the sensor network reports range information and the case where in addition to the range, we also have angular information ...
Hızlı sönümlemeli kanallarda yeni bir uzay-zaman-frekans kodlamalı OFDM sistem tasarımı
(IEEE, 2004)
Bu çalışmada, frekans seçici hızlı sönümlemeli kanallarda telsiz iletişim için bir uzay-zaman-frekans çeşitlemesi yöntemi önerilmiştir. Önerilen yöntem, OFDM tekniğini kullanarak frekans seçici kanalı uygun hale getirdikten ...
Tip singularity of the electromagnetic field at the apex of a material cone
(Springer-Verlag Berlin, 2004)
The tip Singularity of the electromagnetic field at the apex of a cone is investigated in its most general framework. To this end one considers, without loss of generality, a circularly symmetric cone which separates two ...
Theoretical calculation of the kinetic coefficient of normal crystal growth
(Trans Tech Publications Ltd, 2004)
An expression for the velocity u of migration of a diffuse simple crystal-melt interface has been derived on the basis of the theory of atomic mobility in supercooled liquids: u = K-0 (T / T-m) DeltaT, where DeltaT = T-m ...
Fluctuation theory of the liquid-glass transition
(Trans Tech Publications Ltd, 2004)
The glassy state and the character of the liquid-glass transition from undercooled liquid to amorphous solid is one of the biggest challenges of our time. In spite of significant progress we still cannot explain accurately ...
Representation of speech signals by single signature base function within optimum frame length
(IEEE, 2000)
Before this study, we proposed a novel method to represent signals in terms of, so called, “Signature Base Functions-SBF" which were extracted from the physical features of the waveform under consideration. SBF were ...
