Presents a new image magnification algorithm that produces high frequency components of
the spectrum of an image. To estimate high frequency components, the authors investigate …

Time aliasing methods of spectrum estimation alter the time representation of a signal for the
purpose of improving its frequency domain representation. Time aliasing allows …

In this paper, we develop high resolution nonparametric spectrum estimation methods using
basis selection methodology. As opposed to standard minimisation of the l/sub 2/norm of the …

The authors address the problem of support recovery with multiple measurement vectors
(MMV) in this study. The scale of an MMV is reduced by using the singular value …

In this paper we investigate the use of the Affine Scaling Transformation (AST) family of
algorithms in solving the sparse signal recovery problem of harmonic retrieval for the DFT …

Regularization and interpolation of prestack seismic data have become an essential part of
modern data preconditioning flows before imaging and inversion. In this paper, we present a …

The paper develops a new technique enhancing synthetic aperture radar (SAR) resolution
as well as suppressing sidelobes based on adaptive weighting technique. Spatially Variant …

The content-This paper describes the procedure of application Adaptive Weighted Norm
Extrapolation (AWNE) method on stripmap SAR image which was formed using Doppler …

Today's professional audio systems consist of expensive devices that require elaborate
wiring. Changes to installations are complex and errors are hard to localize. System …
