O número de dispositivos Internet das Coisas (IoT) aumentará rapidamente. Nos sistemas de comunicação móvel da próxima geração, uma estação base (BS) deve acomodar efetivamente um grande número de dispositivos IoT. Para resolver este problema, propusemos um novo sistema de acesso múltiplo não ortogonal (NOMA) de link ascendente que também pode ser utilizado para comunicação de baixa latência. Desenvolvemos e avaliamos o sistema através de simulação computacional. Este artigo descreve experimentos conduzidos em um sistema protótipo em ambientes reais. O artigo mostra os resultados dos experimentos quando 3 equipamentos de usuário fixos (UEs) e 2 UEs móveis transmitiram sinais simultaneamente para uma BS e então a BS separou os sinais sobrepostos usando cancelamento de interferência sucessiva (SIC). Também avaliamos técnicas de transmissão de repetição (RT) e diversidade de recepção espacial (SD) empregadas para melhorar o desempenho de separação de sinal para sistemas NOMA. Os resultados dos experimentos confirmam que o sistema que não usa SD nem RT poderia separar em média 3.5 sinais de UEs, enquanto empregando SD ou RT poderia fazer o número aumentar para 4.1 e 4.0, respectivamente. Quando tanto SD quanto RT foram empregados, o número subiu para 4.4.

Abstract: The number of Internet-of-Things (IoT) devices will increase rapidly. In next-generation mobile communication systems, a base station (BS) must effectively accommodate massive numbers of IoT devices. To address this problem, we have proposed a novel up-link non-orthogonal multiple access (NOMA) system that can also be utilized for low latency communication. We have developed and evaluated the system through computer simulation. This paper describes experiments conducted on a prototype system in actual environments. The paper shows results of the experiments when 3 fixed user equipments (UEs) and 2 mobile UEs transmitted signals simultaneously to a BS and then the BS separated superimposed signals using successive interference cancellation (SIC). We also evaluated repetition transmission (RT) and space receive diversity (SD) techniques employed to enhance the signal separation performance for NOMA systems. The results of the experiments confirm that the system using neither SD nor RT could separate 3.5 UEs' signals on average while employing either SD or RT could make the number increase to 4.1 and 4.0, respectively. When both SD and RT were employed, the number rose to 4.4.
