Hardware And Software For Reproducible Research In Audio Array Signal Processing

René Beuchat, Paul Hurley, Robin Scheibler, Hanjie Pan, Sepand Kashani, Matthieu Martin Jean-André Simeoni, Eric Bezzam, Basile Gérard Pierre Bruneau, Corentin Ferry

In our demo, we present two hardware platforms for prototyping audio array signal processing. Pyramic is a 48-channel microphone array fitted on an FPGA and Compact Six is a portable microphone array with six microphones, closer to the technical constraint ...

LEAP: Looking beyond pixels with continuous-space EstimAtion of Point sources

Martin Vetterli, Paul Hurley, Thierry Blu, Hanjie Pan, Matthieu Martin Jean-André Simeoni

Context. Two main classes of imaging algorithms have emerged in radio interferometry: the CLEAN algorithm and its multiple variants, and compressed-sensing inspired methods. They are both discrete in nature, and estimate source locations and intensities on ...

Flexarray: Random phased array layouts for analytical spatial filtering

Paul Hurley, Matthieu Martin Jean-André Simeoni

We propose a method for designing phased-arrays according to a given, analytically-specified, target beamshape. Building on the flexibeam framework, antenna locations are sampled from a probabilistic density function. Naturally scalable with the number of ...

Blind calibration of sensors of sensor arrays

Paul Hurley, Sanaz Kazemi, Matthieu Martin Jean-André Simeoni, Giovanni Cherubini

Embodiments include methods for calibrating sensors of one or more sensor arrays. Aspects include accessing one or more beamforming matrices respectively associated to the one or more sensor arrays. Source intensity estimates are obtained for a set of poin ...

Imaging in radio interferometry by iterative subset scanning using a modified amp algorithm

Paul Hurley, Sanaz Kazemi, Matthieu Martin Jean-André Simeoni, Giovanni Cherubini

Imaging techniques in radio interferometry often face a significant challenge posed by the large number of antenna signals received, from which the image information needs to be extracted. Beam- forming is envisaged to reduce the rate required for transpor ...
