Telemetry system for sensing applications in lossy media

Anja Skrivervik, Francesco Merli, Eric Meurville, Léandre Bolomey

Wireless communications in lossy media encounter growing interest, with applications as telemedicine, ground sensing, remote pipeline sensing, and food quality testing among others. As an application, an autonomous implantable Body Sensor Node for monitori ...

Iterative method for zero-order suppression in off-axis digital holography

Christian Depeursinge, Nicolas Pavillon

We propose a method to suppress the so-called zero-order term in a hologram, based on an iterative principle. During the hologram acquisition process, the encoded information includes the intensities of the two beams creating the interference pattern, whic ...

Signal Processing in Space and Time : A Multidimensional Fourier Approach

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 ...

Graph-based regularization for spherical signal interpolation

Pascal Frossard, Tamara Tosic

This paper addresses the problem of the interpolation of 2-d spherical signals from non-uniformly sampled and noisy data. We propose a graph-based regularization algorithm to improve the signal reconstructed by local interpolation methods such as nearest n ...
