Conception de schémas et récepteurs avancés pour le SCMA et la transmission MIMO non cohérente dans les futurs réseaux sans fil

Abstract : Driven by the demand of connectivity and fast development of multimedia,the sixth generation (6G) of wireless networks has recently been under discussion.In this thesis, we study three promising schemes for the 6G, which are sparsecode multiple access (SCMA), non-coherent (NC) multiple-input multiple-output (MIMO) and single-user (SU) multidimensional transmission. Firstly, we work on the iterative multiuser detection (MUD) algorithms in both simple and highly overload SCMA transmission. Beside, we propose two pruning algorithms and introduce alow-complexity sphere decoding-based SCMA detector. Next, the Grassmannian constellation construction for NC MIMO systems is studied. Two autoencoder-based schemes are proposed and evaluated. Lastly, we take advantage of DL techniques and introduce a novel approach for designing multidimensional constellations in the SU multidimensional transmission.
