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 ...

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 ...
