On the extraction of the channel allocation information in spectrum pooling systems
(IEEE, 2007-04)
The spectrum pooling strategy allows a license owner to share a part of his licensed spectrum with a secondary wireless system (the rental system, RS) during its idle times. The coexistence of two mobile systems on the ...
Analysis of self-noise in a clock recovery system with a high-order nonlinearity
(IEEE-INST Electrical Electronics Engineers Inc, 2003-11)
This correspondence presents a new technique to compute efficiently the spectra of the in-phase (I) and quadrature (Q) components as well as the cross-spectrum of the in-phase and quadrature (I-Q) components of self-noise ...
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 ...
A new method for the source localization in sectionally homogeneous bounded domains involving finitely many inner interfaces of arbitrary shapes
(Pergamon-Elsevier Science, 2001-05)
A new method to localize a static point source buried in a nonhomogeneous bounded domain composed of finitely many homogeneous parts separated by interfaces of arbitrary shapes was established. The source can be a simple ...
Predictive vector quantization of 3-D mesh geometry by representation of vertices in local coordinate systems
(Elsevier Inc, 2007-08)
In predictive 3-D mesh geometry coding, the position of each vertex is predicted from the previously coded neighboring vertices and the resultant prediction error vectors are coded. In this work, the prediction error vectors ...
Air interface identification for Software Radio systems
(Elsevier GMBH, 2007)
Reconfigurable Software Radio (SR) equipment is considered as the next evolutionary step in the mobile communications. One of the most crucial properties of a SR terminal is that it is capable of using a wide range of air ...
Linear expansions for frequency selective channels in OFDM
(Elsevier GMBH, 2006)
Modeling the frequency selective fading channels as random processes, we employ a linear expansion based on the Karhumen-Loeve (KL) series representation involving a complete set of orthogonal deterministic vectors with a ...
Optimal nonlinear controller design for flexible robot manipulators with adaptive internal model
(INST Engineering Technology-IET, 2007-05)
Developing nonlinear adaptive and robust controllers for a two-link flexible robot arm is the main objective of this research. The dynamic state feedback controller is used to achieve robust regulation of the rigid modes ...
Derivation of the Lorentz transformation from the Maxwell equations
(VSP BV, Brill Academic Publishers, 2005)
The Special Theory of Relativity had been established nearly one century ago to conciliate some seemingly contradictory concepts and experimental results such as the Ether, universal time, contraction of dimensions of ...
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 ...
