A generalization of the Wiener-Hopf approach to direct and inverse scattering problems connected with non-homogeneous half-spaces bounded by n-part boundaries
(Oxford Univ Press, 2000-08)
The classical Wiener-Hopf method connected with mixed two-part boundary-value problems is generalized to cover n-part boundaries. To this end one starts from an ad-hoc representation for the Green function, which involves ...
Analysis of layered media terminated with an impedance surface varying in lateral directions
(Springer-Verlag Berlin, 2000)
Determination of the constitutive parameters of a region from data provided by remote sensing is an extremely interesting and important topic from various points of view. In a large class of problems of this type, the ...
Scattering of electromagnetic waves by a rectangular impedance cylinder
(Elsevier Science, 2000-04)
A uniformly valid asymptotic solution is developed for the diffraction of a high-frequency wave by an infinitely long rectangular cylinder having different impedance walls. The incident wave is generated by a line source ...
On the equilibrium of a rigid body suspended by a set of linear springs
(John Wiley & Sons, 2000-08)
In this paper an approach is described for determining equilibrium states of a rigid body suspended elastically in space by a set of linear springs. This system is considered as a two-terminal generalized spring with ...
Confluent edge conditions for the electromagnetic wave at the edge of a wedge bounded by material sheets
(Elsevier ScienceWave Motion, 2000-07)
The edge conditions which dictate the asymptotic behaviour of the electromagnetic field near the edges play a crucial role in solving boundary-value problems involving boundaries having edges. In analytical studies they ...
The concept of confluence and the edge conditions for a wedge bounded by material sheets
(IEEE, 2000)
The edge conditions which dictate the asymptotic behaviour of the electromagnetic field near the edges play a crucial role in solving boundary-value problems involving boundaries having edges, in analytical studies they ...
A new algorithm for joint time and phase synchronization in OFDM systems
(IEEE, 2000)
In this paper, a computationally efficient algorithm is presented for joint maximum likelihood (ML) timing and carrier phase synchronization of OFDM systems employing M-PSK modulation scheme with additive Gaussian noise, ...
Generation of optimum signature base sequences for speech signals
(IEEE, 2000)
In our previous publications [1-6], 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. ...
Joint ML timing and phase estimation in OFDM systems using the EM algorithm
(IEEE, 2000)
In this paper, a computationally efficient algorithm is presented for joint maximum likelihood (ML) timing and carrier phase estimation of OFDM systems employing M-PSK modulation scheme with additive Gauissian noise, based ...
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 ...
