Head : Marie CHABERT
The research activities of the “Signal & Communications” group are currently divided into two main areas:
- Statistical signal & image processing: analysis and representation, inverse problems and computational imaging, machine learning
- Signal for communications: waveform design, digital receivers, communication system modeling and performance.
Statistical signal & image processing
Prominent research activities in statistical signal & image processing conducted by the SC group are currently dedicated to the following research topics:
- Signal & image analysis and representation
- non-uniform sampling and reconstruction
- spectral analysis: empirical mode decomposition, AM/FM decomposition
- time-frequency analysis: reassignment and synchrosqueezing
- multiscale, multi-resolution and multifractal analysis: scale invariance, self-similarity, local regularity, texture analysis
- Inverse problems and computational imaging
- restoration: denoising, deconvolution
- single-image super-resolution
- fusion of multi-band images (e.g., multi- and hyperspectral pansharpening)
- Machine learning for signal & image processing
- blind source separation: independent component analysis (ICA), nonnegative matrix factorization (NMF)
- representation learning: dictionary learning, subspace learning, adaptive and fast transforms
- structured modeling: sparse, anti-sparse and low-rank models
These different problems are tackled using various methodological and theoretical tools such as:
- Bayesian modeling and computation
- (hierarchical) Bayesian inference
- latent variable models, hidden Markov models, Markov random fields
- Bayesian nonparametrics: Beta, Dirichlet and Gaussian processes
- Markov chain Monte Carlo (MCMC) algorithms: Metropolis-Hastings, (partially collapsed) Gibbs samplers, reversible jump algorithms, Hamiltonian Monte Carlo, proximal-MALA
- approximate Bayesian computations (ABC), variational Bayesian methods
- Deterministic and stochastic optimization
- splitting and proximal algorithms
- augmented Lagrangian methods
- majorization-minimization algorithms
- Monte Carlo integrations and approximations
These research activities are carried out in various applicative fields, namely:
- Geoscience and remote sensing
- hyperspectral imaging: spectral unmixing, nonlinearity and variability detections, segmentation/classification, fusion (e.g., pansharpening)
- multi-temporal image analysis: change detection, unmixing
- conventional and delay/Doppler altimetry: modeling and parameter estimation
- Biomedical imaging and engineering
- segmentation and unmixing of 3D+t TEP images
- ultrasound imaging: fast acquisition and compressed sensing, segmentation/classification
- P- and T-waves detection and delineation in ECG
- source localization in EEG
- hemodynamic brain parcellation in fMRI
- multiscale and multifractal analysis of biomedical signals (fMRI, ECG)
- gene expression factor analysis: identification of disease signature (e.g., influenza)
- Diagnosis and condition monitoring
- detection and diagnosis of mechanical and bearing faults in electrical machines
- processing of anemometric and inertial data in flight control systems
- aging modeling for prognosis in electrical engineering
- Audio and music processing
- music signal decomposition
- multichannel source separation
- audio restoration
- music chord recognition
- Microscopy and spectroscopy
- EELS spectrum-image analysis
- spectrochemical analysis
- magnetic resonance force microscopy (MRFM) imagery
- Art investigation and cultural heritage
- audio-guided video synthesis for modern art
- texture analysis and classification of photographic prints

- BICM schemes for nonlinear code-shift keying modulation
- Structured coding schemes for non-ergodic channels
- compressed sensing approach for indoor and outdoor localization of users over multipath large scale MIMO channels
- Spatial coupling for serially concatenated systems
- Waveform design and coding for IoT (BPSK, code-shift keying modulation, Chirp Spreaded modulation, FSK based…)
- MIMO Radar
- Multiple access and random access
- Methods for Random Access: MARSALA, MUSCA and SPOTiT schemes.
- IoT by satellite
- Identification, equalization and detection
- iterative schemes for sparse graph-based coded continuous phase modulation (CPM)
- iterative detection of bit-interleaved code modulation system over frequency selectif channels
- low-complexity frequency domain detection and synchronization methods
- unrolled deep expectation-propagation (EP) detection
- expectation/Belief-propagation (EP/BP) based detection schemes
- detection in nonlinear channels using mutual information optimized neural networks (NN)
- detection in nonlinear channels using linear low complexity MAP based or MMSE based detector for Nyquist and Faster than Nyquist
- classification of modulations
- Multicarrier systems and filterbanks
- orthogonal frequency-division multiplexing (OFDM)
- multicarrier code division multiple access (CDMA)
- Cooperative communications
- stochastic geometry for interference modeling
The applications, in the general frameworks of wireless and satellite communications, are mainly related to:
- Satellite communications
- telemetry coded waveforms for the next Ariane spacecraft generation
- digital broadcasting
- IoT by satellite using Low Earth Orbit (LEO) constellations
- Wireless communications
- unmanned aerial vehicle (UAV)
- UAV-based mobile targets tracking
- generation and management of adaptive UAV trajectories
- internet-of-things (IoT)
- ad-hoc networks
- vehicular networks
