Thèse à CentraleSupélec (IETR) : Non Orthogonal Multiple Access for public safety communications in 5G context
LABORATORY : IETR (CNRS lab.)
RESEARCH TEAM : SCEE – CentraleSupélec (Rennes)
TOPICS : Digital Communications and signal processing
DATES : Sept. 2020 to Sept. 2023
Context of the study
PMR (Private Mobile Radio) communications are used to set up links for security forces (police, firemen, ….) and are based on low data rate standards (TETRA, TETRAPOL, …). In parallel, mobile communications standards (3G, LTE, 4G) developed by 3GPP propose huge data bit rates which could benefit to PMR radios as well. So a big issue has surfaced up so as to include some PMR specificities in 3GPP (3G, 4G) including smart switching between unicast/multicast/broadcast topologies. Now the objective is to include PMR functionalities into 5G.
In this context, the PhD thesis intends to investigate the benefit of multiple access modes such as NOMA techniques (Non Orthognal Multiple Access) so as to optimize the spectral resources to switch from unicast/multicast/broadcast and investigate the potential of the broadcast mode. This is supposed to take into account the 5G specificities and the associated waveforms (OFDM and MIMO). The theoretical issues will be considered (optimal power to users, derivation of performance, adaptive process, switching mode, ….).
This PhD position is open at IETR (Institut d’Electronique et de Télécommunications de Rennes), a CNRS research lab mostly located in Rennes (France). The works will be done in SCEE group (Signal Communications and Embedded Electronics) of IETR, at CentraleSupélec (Rennes).
Key words: NOMA, 5G, OFDM
