A synthetic aperture imaging system using surface wave modes
(IEEE, 1995)
A synthetic aperture acoustic imaging system with a novel inversion algorithm is described. Data is obtained by using a transducer insonifying the sample surface at a critical angle which is excited by a short electrical ...
A comparison of two methods for fusing information from a linear array of sonar sensors for obstacle localization
(IEEE, 1995)
The performance of a commonly employed linear array of sonar sensors is assessed for point-obstacle localization intended for robotics applications. Two different methods of combining time-of-flight information from the ...
The discrete fractional Fourier transformation
(IEEE, 1996)
Based on the fractional Fourier transformation of sampled periodic functions, the discrete form of the fractional Fourier transformation is obtained. It is found that only for a certain dense set of fractional orders such ...
Cost-efficient approximation of linear systems with repeated and multi-channel filtering configurations
(IEEE, 1998-05)
It is possible to obtain either exact realizations or useful approximations of linear systems or matrix-vector products arising in many different applications, by synthesizing them in the form of repeated or multi-channel ...
Accurate plane-wave excitation in the FDTD method
(IEEE, 1997)
Different techniques are developed to implement plane-wave excitation on the finite-difference time-domain (FDTD) method, such as the initial-condition, the hard-source, and the connecting-condition techniques, for the ...
An efficient algorithm to extract components of a composite signal
(IEEE, 2000)
An efficient algorithm is proposed to extract components of a composite signal. The proposed approach has two stages of processing in which the time-frequency supports of the individual signal components are identified and ...
A survey on optimal stochastic signaling and detector randomization
(IEEE, 2011)
In this paper, a survey on stochastic signaling and detector randomization is presented for average power-constrained binary communications systems. First, the case of a single fixed detector at the receiver is considered, ...
Determining F2 layer parameters via optimization using IRI model and IONOLAB TEC estimations
(IEEE, 2011)
We know that F2 layer of the ionosphere is most important layer in the progaration of high frequency (HF) waves. In this study, The relation of the height (HmF2) and the critical frequency (FoF2) of F2 layer-among the ...
ERP source reconstruction by using Particle Swarm Optimization
(IEEE, 2009)
Localization of the sources of Event Related Potentials (ERP) is a challenging inverse problem, especially to resolve sources of neural activity occurring simultaneously. By using an effective dipole source model, we propose ...
A Bayesian approach to respiration rate estimation via pulse-based ultra-wideband signals
(IEEE, 2009)
In this paper, theoretical limits on estimation of respiration rates via pulse-based ultra-wideband (UWB) signals are studied in the presence of prior information about respiration related signal parameters. First, a ...
