Investigating new PHY-Layer technologies to reach beyond-5G data rates and capacities
BRAVE is a collaborative research project started in January 2018, that aims at creating new physical-layer (PHY) techniques devoted to beyond-5G wireless communications. The partners (Siradel, Central-Supélec, CEA-Leti and ANFR) are designing new high-data-rate and energy-efficient waveforms that operate in frequencies above 90 GHz. Application to scenarios such as kiosks, backhauling, hotspots are assessed to evaluate the benefit of the proposed technology.
Funded by the French Research Agency ANR, the BRAVE project will go to its end in September 2021.
The consortium is combining skills from an industry (Siradel), an academic laboratory (Centrale-Supélec), a research institute (CEA-Leti) and a regulator (ANFR), which are all familiar with collaborative research and recognized in the field of wireless innovation. The partners bring complementary skills to efficiently tackle the different challenges of the project: regulation, signal processing, realistic modelling of the PHY-layer, and software-based evaluation.
Sub-THz frequencies & Regulation
Frequencies above 90 GHz offer opportunities for huge band-widths, up to several tens of GHz, which is required to increase data rates and network capacities beyond 5G performance. BRAVE is investigating the sub-THz spectrum from 90 to 300 GHz.Read more
The BRAVE technology applies to short-range or line-of-sight communication scenarios that must deliver ultra-high data rates, in order to solve congestion (in backhaul network or server farms) or enable future challenging aplications (e.g. multi-user high-quality VR).Read more
BRAVE revisit the PHY-layer by looking back on single-carrier (SC) modulations, thus allowing for improved spectral efficiency and reduced power consumption (i.e. from lower PAPR). Indeed the line-of-sight transmission and the use of large antenna arrays make the propagation channel favourable to SC.Read more
Modelling and Simulation
Study and modelling of the propagation and RF impairments at frequencies above 90 GHz aims at: – Implementing realistic link- and system-level simulators. – Designing the new air interface based on well-understood physical constraints. – Evaluating and demonstrating B5G scenarios.Read more
