Organisation
The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas :
• defence and security,
• nuclear energy (fission and fusion),
• technological research for industry,
• fundamental research in the physical sciences and life sciences.
Drawing on its widely acknowledged expertise, and thanks to its 16000 technicians, engineers, researchers and staff, the CEA actively participates in collaborative projects with a large number of academic and industrial partners.
The CEA is established in ten centers spread throughout France

Division description
The Leti, an institute under the Direction of Technological Research at CEA, is commissioned with transferring breakthrough innovations to the industry. Its core expertise lies in microelectronics technologies, as well as in circuits, components and systems integration, hence contributing to the technological development and maturation of a variety of application domains, including the Internet of Things, artificial intelligence, augmented reality, connected health, industry 4.0, autonomous/assisted mobility...
Description de l'unité
Within Leti, the "Laboratory of Radio Signals, Protocols, and Platforms" (LS2PR) aims at studying advanced wireless systems and implementing them on embedded electronic devices. The laboratory's research areas encompass algorithms design at the radio physical layer (incl. waveforms definition, along with associated signal processing methods) and cross-layer protocols (incl. spectrum access and networking), radio resource optimization and orchestration for communication, computing, and control in networks, the definition of connectivity architectures, as well as wireless localization and sensing techniques.
The developed wireless communication solutions address the needs of specific or customized applications (such as energy-constrained, latency-critical, and/or high-speed communications), as well as those of future generations of cellular networks (typically, beyond 5G and 6G).

Job description
CONTEXT :
The recent trend in next-generation wireless networks (6G), known as ISAC (Integrated Sensing and Communication), aims at incorporating localization, detection, and mapping functionalities alongside the usual data communication services. These functions are expected to enhance network performance through spatial adaptation strategies, as well as to enable more efficient and more frugal communications through data contextualilzation. In the same 6G context, Reconfigurable Intelligent Surfaces (RIS), which can be controlled as low-complexity electromagnetic mirrors or lenses, have also been considered recently for shaping the radio propagation environment on purpose. For instance, this capability could be beneficial to improve the accuracy, coverage, and continuity of the localization service.
In the frame of the proposed research mission, we ambition to develop and experimentally validate (by means of dedicated measurement campaigns and simulations) some innovative estimation and control algorithms that can leverage the deployment of multiple RISs to enable the positioning/tracking of connected users, as well as of passive objects or obstacles. This research will take into account the specificity of both real RIS hardware prototypes and RIS-based multipath channels, which both have been characterized at CEA-Leti at millimeter-wave frequencies (i.e., around 26-28 GHz).
TASKS :
- Survey and analysis of recent related State-of-the-Art contributions ;
- Design of RIS-based estimation algorithms, as well as of supporting control and signaling mechanisms, for localization, sensing and mapping, out of mmWave communication links under mobility, while accounting for realistic RIS hardware limitations.
- Validation of some of the previous algorithmic proposals, by means of both measurement data and simulation data ;
- Participation to the ellaboration of new RIS-enabled measurement campaigns (incl. the specification of the measurement setup and scenarios, field data collection, conditioning and post-processing, etc.) ;
- Contributions to related collaborative research projects at both national and European levels (incl. participation to conference calls and meetings, contributions to technical deliverables and reporting activities) ;
- Participation to the scientific dissemination of achieved results (through journals and conference papers) ;
Applicant Profile
- General knowledge in radio signal processing and modeling, including for instance (whenever possible): estimation and detection theory (e.g., Bayesian estimation and statistical inference, processes filtering, derivation of theoretical bounds...), multipath channel modeling, multi-antenna and MIMO processing techniques, high-resolution channel estimation algorithms ;
- General skills required in algorithms design, including (whenever possible) a fair understanding of distributed and hierarchical approaches;
- Proficiency in digital simulation tools (including Matlab);
- Specific knowledge in wireless localization, radio mapping, radar, and/or reconfigurable intelligent surfaces would be a highly valued plus;
- A track record of past/on-going scientific dissemination activities (i.e., journal publications or conference articles) would be a highly valued plus.
