A transmissão massiva de múltiplas entradas e saídas (MIMO), na qual o número de antenas é consideravelmente maior que o número de terminais de usuário, tem atraído a atenção como uma tecnologia chave nos sistemas de comunicação móvel da próxima geração, porque permite melhorias no serviço mitigação de área e interferência com processamento simples de sinal. MIMO massivo multifeixe empregando seleção de feixe de alta potência na parte analógica e um algoritmo cego na parte digital, como o algoritmo de módulo constante que não precisa de informações de estado do canal, foi proposto e demonstrou oferecer alta eficiência de transmissão. Neste artigo, a fim de obter maiores taxas de transmissão e eficiência de comunicação, propomos um método de seleção de feixe que utiliza apenas informações de amplitude de múltiplos feixes. Além disso, este método pode ser realizado através do processamento de sinal com uma configuração simples e é altamente adequado para MIMO massivo analógico-digital híbrido, o que é vantajoso em termos de custo e consumo de energia. Aqui, a eficácia do método proposto é verificada por simulação computacional.

Abstract: Massive multiple-input multiple-output (MIMO) transmission, in which the number of antennas is considerably more than the number of user terminals, has attracted attention as a key technology in next-generation mobile communication systems, because it enables improvements in the service area and interference mitigation with simple signal processing. Multi-beam massive MIMO employing high-power beam selection in the analog part and a blind algorithm in the digital part, such as the constant modulus algorithm that does not need channel state information, has been proposed and shown to offer high transmission efficiency. In this paper, in order to realize higher transmission rates and communication efficiency, we propose a beam-selection method that uses multi-beam amplitude information only. Furthermore, this method can be realized through signal processing with a simple configuration and is highly suitable for hybrid analog-digital massive MIMO, which is advantageous in terms of cost and power consumption. Here, the effectiveness of the proposed method is verified by computer simulation.
