Dans les systèmes de communications mobiles de cinquième génération (5G), les systèmes d'accès multiple non orthogonal (NOMA) sans autorisation ont été envisagés comme un moyen de prendre en charge les nombreuses connexions sans fil requises pour les appareils Internet des objets (IoT). Dans les schémas NOMA, l'amélioration de la capacité du système et la simplification du protocole de transmission sont obtenues, et un test de surcharge de plus de cent pour cent des échantillons de transmission est effectué. L'accès multiple partagé multi-utilisateurs (MUSA) a été proposé comme schéma représentatif du NOMA. Cependant, les performances de MUSA n'ont pas été entièrement analysées ni comparées à d'autres systèmes NOMA ou à accès multiple orthogonal. Par conséquent, dans cette étude, nous analysons théoriquement et numériquement les performances de MUSA dans des environnements d'évanouissement de liaison montante et les comparons à l'accès multiple par répartition orthogonale de la fréquence (OFDMA), à l'OFDMA basé sur l'accès multiple par répartition spatiale, à la signature de faible densité et à l'accès multiple à code clairsemé. . Les caractéristiques et la supériorité de MUSA sont alors précisées.

Abstract: In fifth-generation mobile communications systems (5G), grant-free non-orthogonal multiple access (NOMA) schemes have been considered as a way to accommodate the many wireless connections required for Internet of Things (IoT) devices. In NOMA schemes, both system capacity enhancement and transmission protocol simplification are achieved, and an overload test of more than one hundred percent of the transmission samples over conducted. Multi-user shared multiple access (MUSA) has been proposed as a representative scheme for NOMA. However, the performance of MUSA has not been fully analyzed nor compared to other NOMA or orthogonal multiple access schemes. Therefore, in this study, we theoretically and numerically analyze the performance of MUSA in uplink fading environments and compare it with orthogonal frequency division multiple access (OFDMA), space division multiple access-based OFDMA, low-density signature, and sparse code multiple access. The characteristics and superiority of MUSA are then clarified.
