Sequence estimation with transmit diversity for wireless communications
(Urban & Fischer Verlag, 2003)
In this paper, an optimum sequence estimation algorithm for wireless systems with Alamouti's two transmitter diversity in the presence of multipath fading is proposed. The algorithm is based on a jointly iterative channel ...
Signals of chaotic behavior in PMMA
(Pergamon-Elsevier Science, 2003-07)
The time evolution of the current passing through PMMA polymer thin films under 10 V at 23degreesC (296 K) was sampled at intervals ranging from 1 to 20 s. The data showed chaotic behavior in the context of pinned charge ...
Failure of an exchange-rate-based stabilization plan in Turkey
(M E Sharpe, 2003-02)
The Turkish exchange-rate-based stabilization plan adopted in 2000 has been a spectacular failure, lasting a mere fourteen months despite a relatively flexible peg regime and preannounced exit strategy. The final three ...
Confluent tip singularity of the electromagnetic field at the apex of a material cone
(Elsevier Science, 2003-09)
The tip singularity of the electromagnetic field at the apex of a cone (conical sheet) is investigated in its most general framework. To this end one considers, without loss of generality, a circularly symmetric cone which ...
On a class of functional equations of the Wiener-Hopf type and their applications in n-part scattering problems
(Oxford Univ Press, 2003-12)
An asymptotic theory for the functional equation K-phi=f, where K : X-->Y stands for a matrix-valued linear operator of the form K=K1P1+K2P2+...+KnPn, is developed. Here X and Y refer to certain Hilbert spaces, {P-alpha} ...
Joint channel tracking and symbol detection for OFDM systems with Kalman filtering
(Urban & Fischer Verlag, 2003)
This paper proposes a new joint channel tracking and symbol detection scheme for pilot symbol-assisted OFDM systems in multipath fading. The proposed scheme uses Kalman filters for both channel tracking and subsequent ...
Contributions of higher order terms to nonlinear waves in fluid-filled elastic tubes: strongly dispersive case
(Pergamon-Elsevier Science, 2003-07)
In the present work, employing the nonlinear equations of an incompressible, isotropic and elastic thin tube and the approximate equations of an incompressible inviscid fluid, and then utilizing the modified reductive ...
Amplitude modulation of nonlinear waves in a fluid-filled tapered elastic tube
(Wiley-V C H Verlag, 2003)
In the present work, treating the arteries as a tapered, thin walled, long, and circularly conical prestressed elastic tube and using the reductive perturbation method, we have studied the amplitude modulation of nonlinear ...
On the derivation of some non-linear evolution equations and their progressive wave solutions
(Pergamon-Elsevier Science, 2003-06)
In the present work, utilizing the reductive perturbation method, the non-linear equations of a prestressed viscoelastic thick tube filled with a viscous fluid are examined in the longwave approximation and some evolution ...
Amplitude modulation of nonlinear waves in fluid-filled tapered tubes
(Consultants Bureau, 2003-12)
We study the modulation of nonlinear waves in fluid-filled prestressed tapered tubes. For this, we obtain the nonlinear dynamical equations of motion of a prestressed tapered tube filled with an incompressible inviscid ...
