Introduction
My fields of interest cover the design System-On-Chip for Signal Processing algorithms. So I work on 2 domains : signal processing, mathematics and digital component architectures. What is the adequation between the algorithm and the architecture ? Sometimes, if the algorithm doesn't fit (mainly time performance), we can change the architecture. And sometimes, we can do the reverse : modify the algorithm to take full advantage of the architecture.

Conference Paper
Time-Sensitive Networking (TSN) describes a set of features extending the functionalities and Quality of Service (QoS) of standard Ethernet to enable determinism, reliability and reconfigurability, key requirements for Industry 4.0. The TSN profile for industrial automation (IEC/IEEE 60802 standard) defines specific options to favor reliability and...

Artificial Neural Networks (ANNs) are biologically inspired algorithms especially efficient for pattern recognition and data classification. In particular, Recurrent Neural Networks (RNN) are a specific type of ANNs which model and process sequences of data that have temporal relationship. Thus, it introduces interesting behavior for embedded syste...
Article
The effect of gamma-ray and neutron radiations on the Variable Retention Time (VRT) phenomenon occurring in Dynamic Random Access Memory (DRAM) is studied. It is shown that both ionizing radiation and non-ionizing radiation induce VRT behaviors in DRAM cells. It demonstrates that both Si/SiO2 interface states and silicon bulk defects can be a sourc...

A System-On-Chip design and synchronization details of a navigation receiver are presented. The architecture of the GNSS receiver is easily modifiable and offers the capability of accurate time management, thanks to the use of a co-design approach. The purpose of such a platform is to allow real time validation of research algorithms. A secondary a...

Full-text available
A System-On-Chip design and implementation of a navigation receiver is presented. The use of a co-design GNSS architecture aims to offer both the capability of a critical management of time and of an easily modifiable architecture. The full implementation is still undergoing, but preliminary results demonstrate accuracy, flexibility and ease of use...

Space Vehicle (SV) life span depends on its station keeping capability. Station keeping is the ability of the vehicle to maintain position and orientation. Due to external perturbations, the trajectory of the SV derives from the ideal orbit. Actual positioning systems for satellites are mainly based on ground equipment, which means heavy infrastruc...
Conference Paper
Full-text available
In the context of linear discrete state-space (LDSS) models, we generalize a result lately introduced in the restricted case of invertible state matrices, namely that the linear minimum variance distortionless response (LMVDR) filter shares exactly the same recursion as the linear least mean squares (LLMS) filter, aka the Kalman filter (KF), except...
Article
Full-text available
For linear discrete state-space (LDSS) models, under certain conditions, the linear least mean squares (LLMS) filter estimate has a recursive format, aka the Kalman filter (KF). Interestingly, the linear minimum variance distortionless response (LMVDR) filter, when it exists, shares exactly the same recursion as the KF, except for the initializatio...

For linear discrete state-space models, under certain conditions, the linear least-mean-squares filter estimate has a convenient recursive predictor/corrector format, aka the Kalman filter. The purpose of this paper is to show that the linear minimum variance distortionless response (MVDR) filter shares exactly the same recursion, except for the in...
Conference Paper
The increase in integration density and the requirement of low power supplies to reduce energy consumption can make circuits more and more sensitive to hardware errors. The loss of robustness increases with process/voltage and temperature (PVT) variations. This demo presents a platform used first to implement a noiseless GPS receiver algorithm. Red...

L’orbite d’un satellite autour de la terre est perturbée en permanence par différents facteurs, tels que lavariation du champ gravitationnel et la pression du vent solaire.

Thesis
Full-text available
The orbit of a satellite around the earth is constantly disturbed by various factors, such as variations in the gravitational field and the solar wind pressure. The drift of the satellite position can compromise the mission, and even lead to a crash or a fall in the atmosphere. The station-keeping operations therefore consist in performing an accur...

In this paper, we present the implementation of the acquisition algorithm of a versatile Global Navigation Satellite System (GNSS) receiver for satellite applications. For versatility purpose, the choice of the receiver algorithms has been motivated by 1) their capability to fulfill the application requirements with a moderate complexity, 2) their...

In contrast with ground applications the GNSS constellations are not optimized for space applications. Moreover, the different types of mission, i.e. Low Earth Orbit (LEO), Medium Earth Orbit (MEO), Geosynchronous Earth Orbit (GEO), have all specific requirements. Our motivation is to define an «Ubiquitous GNSS receiver (UGNSS)», i.e. a single rece...
Article
The trajectory of Space Vehicles (SVs) derives due to external perturbations, such as the variation in the gravitation fields (earth, moon and sun) or the solar pressure effect. The station keeping of SVs is the operation that keeps the satellites in a predefined window. This operation implies that the SV position is known. Actual positioning syste...

This paper presents a programmable DSP board developed for real-time estimation of rigid body orientation. This work takes place in a research project carried out by students. The project consists of unmanned aerial vehicle's (UAV) attitude estimation. This estimation is processed by an Inertial Reference System (IRS) including the TMS320F2812 proc...

The main contribution of this work is the specification of an asynchronous TSN-compliant network for Industry 4.0, FactoRing, that guarantee low bounded jitters and latencies, without the need of global synchronization and complex network planning. Moreover, FactoRing supports ring-based topologies to significantly reduce installation wiring and costs.
Project
The goal of post-quantum cryptography (also called quantum-resistant cryptography) is to develop cryptographic systems that are secure against both quantum and classical computers, and can interoperate with existing communications protocols and networks.
