PERSEUS focuses on the technologies, processing and optimisation of cell-free massive MIMO (CF-mMIMO) networks in the sub-7 GHz frequency band. The combination of CF-mMIMO technology with reconfigurable intelligent surface (RIS) techniques and artificial intelligence (AI) tools represents a very promising solution for ‘beyond-5G’ networks.

NF-PERSEUS aims at increasing the maturity of these techniques towards achieving efficient power and spectral massive access in scalable B5G sub-7GHz networks. The project covers several aspects: (i) the design, manufacturing and testing of RF circuits, reconfigurable intelligent surface (RIS) and antennas, (ii) the development of robust PHY and MAC layers based on signal propagation measurements and the incorporation of hardware imperfection models and (iii) the development of proofs of concept for the practical assessment of the performance of selected algorithms and hardware manufactured in the framework of the project.
