Read more: the CEA-Leti contribution
Within BRAVE, CEA-Leti works on the hardware side of new physical-layer techniques for beyond-5G communications.
Role in the consortium
BRAVE is a collaborative research project started in January 2018. Its partners design new physical-layer techniques, and CEA-Leti contributes the hardware view: what a waveform or receiver algorithm costs in silicon, power and complexity.
This link between theory and implementation helps the consortium discard techniques that look good on paper but cannot be built efficiently.
- Analysis of implementation complexity
- Prototyping of radio and baseband blocks
- Feedback to algorithm designers
Side note: the consortium overview is on the project introduction page.
Work plan
- Start
Requirements capture
Hardware constraints such as power budget, sampling rate and dynamic range are collected from partners.
- Middle
Architecture studies
Candidate transceiver architectures are compared for the proposed waveforms.
- Final
Prototype evaluation
Selected blocks are tested and the measured results are returned to the simulation teams.
Technical focus
Energy per transmitted bit is treated as a design target alongside spectral efficiency.
Non-ideal amplifiers and oscillators are modelled so that receivers are tested under realistic distortion.
Work on sub-terahertz links is connected to the sub-THz studies of the project.
