In this paper, we explore the adoption of Array Signal Processing in Galileo Ground Stations. The main motivation comes from the need of efficiently mitigating multipath and interference sources in order to achieve centimetre accuracy. One of the critical aspects appearing when an array of antennas is implemented resides on the array perturbations and mismodelling. For that reason, this work places...
In this paper, we consider the problem of blind image separation by taking advantage of the sparse representation of the study images in the DCT-domain. Blind source separation (BSS) is an important field of research in signal and image processing. The BSS problem has been considered either directly in the original domain of observations or in a transform domain. The idea behind transform domains...
This paper considers a problem of distributed tracking with consensus on a time-varying graph with noisy communications links. A distributed tracking with consensus algorithm is proposed to handle a time-varying network topology in which every node generates own local tracking estimates and communicates over noisy links. The conditions on the connectivity graph are established so that distributed...
