Tomographic Reconstruction of the Ionospheric Electron Density in term of Wavelets

Ionospheric tomography is a method to investigate the ionospheric electron density in two or three dimensions. In this study, the function-based tomographic technique has been used for regional reconstruction of a 3D tomographic model of the ionospheric electron density using the GPS measurements of the Iranian Permanent GPS Network. Two-dimensional Haar wavelets and empirical orthogonal functi...

CHAPTER 3 V a y e s i a n and Related Methods in Image Reconstruction from Incomplete Data

The problem of obtaining an artifact-free computed tomographic (CT) reconstruction from projection data that are limited in number and possibly angular coverage is a difficult one to solve in general. Similarly, restorations of blurred images are almost always marred by artifacts that appear to be related to the blurring function. These difficulties arise from a fundamental limitation inherent ...

Reconstruction of Network Coded Sources From Incomplete Datasets

We investigate the problem of recovering source information from an incomplete set of network coded data with help of prior information about the sources. This problem naturally arises in wireless networks, where the number of network coded packets available at the receiver may not be sufficient for exact decoding due to channel dynamics or timing constraints, for example. We study the theoreti...
