Distributed Detection Over Adaptive Networks Using Diffusion Adaptation

Ali H. Sayed

We study the problem of distributed detection, where a set of nodes is required to decide between two hypotheses based on available measurements. We seek fully distributed and adaptive implementations, where all nodes make individual real-time decisions by ...

Sparse spectral factorization: Unicity and Reconstruction Algorithms

Martin Vetterli, Yue Lu

Spectral factorization is a classical tool in signal processing and communications. It also plays a critical role in X-ray crystallography, in the context of phase retrieval. In this work, we study the problem of sparse spectral factorization, aiming to re ...

Dataflow Programming for Systems Design Space Exploration for Multicore Platforms

Christophe Lucarz

Nowadays processing systems are asked to support increasing complex and demanding high-performance applications, especially in the signal processing and video processing domains. The design of these systems are becoming extremely challenging because of sev ...

A Signal Processing Approach to Generalized 1-D Total Variation

Dimitri Nestor Alice Van De Ville, Fikret Isik Karahanoglu, Ilker Bayram

Total variation (TV) is a powerful method that brings great benefit for edge-preserving regularization. Despite being widely employed in image processing, it has restricted applicability for 1-D signal processing since piecewise-constant signals form a rat ...

Signal Processing in Space and Time

Francisco Pereira Correia Pinto

Sound waves propagate through space and time by transference of energy between the particles in the medium, which vibrate according to the oscillation patterns of the waves. These vibrations can be captured by a microphone and translated into a digital sig ...

Reionization by UV or X-ray sources

Yves Revaz

We present simulations of the 21-cm signal during the epoch of reionization. We focus on properly modeling the absorption regime in the presence of inhomogeneous Wouthuysen-Field effect and X-ray heating. We ran radiative transfer simulations for three ban ...

Frame Domain Signal Processing: Framework and Applications

Martin Vetterli, Amina Chebira

Besides basis expansions, frames representations play a key role in signal processing. We thus consider the problem of frame domain signal processing, which is more complex and challenging than transform domain processing. Examples of such processing aboun ...

Multimodal Signal Processing: Methods and Techniques to Build Multimodal Interactive Systems

Jean-Philippe Thiran, Hervé Bourlard, Ferran Marqués

Multimodal signal processing is an important new field that processes signals from a variety of modalities - speech, vision, language, text- derived from one source, which aids human-computer and human-human interaction. The overarching theme of this book ...

Integrated receiving circuit and method for radiofrequency and high speed signals

Edoardo Charbon, Marek Gersbach

Integrated receiving circuit for radiofrequency signals comprising: an amplifying element (2) using the multiplication zone (5) of a reverse biased semiconductor junction (3, 4) operating in Geiger mode for amplifying an input radiofrequency signal (Vin) a ...

Implantable ultra-low power DSP-based system for a miniature chemico-rheological biosensor

Peter Ryser, Eric Meurville, Léandre Bolomey

An active implantable chemico-rheological sensor including control electronics, a Digital Signal Processor (DSP) and an RF transceiver has been demonstrated. The ultra-low power system architecture achieves an energy per viscosity measurement of only 16.6m ...
