Esta carta propõe um algoritmo de comutação de formação de feixe adaptativo para sistemas realistas massivos de múltiplas entradas e múltiplas saídas (MIMO) por meio de protótipos. É analisado e identificado que um regime rígido de formação de feixe monomodo é difícil de manter um desempenho superior o tempo todo devido à falta de adaptação à inevitável variação do canal na prática. A fim de lidar com esta questão prática, o mecanismo sistemático de formação de feixe proposto é investigado para permitir a seleção dinâmica entre o erro quadrático médio mínimo e os algoritmos de formação de feixe de grade de feixes, o que melhora o desempenho do downlink do sistema, incluindo taxa de transferência e taxa de erro de bloco. Os benefícios significativos de desempenho e a viabilidade realista foram validados através de testes de campo em redes ativas e análises teóricas. Enquanto isso, o algoritmo de comutação de formação de feixe adaptativo é aplicável ao sistema de comunicação celular duplex por divisão de tempo de quarta e quinta geração usando tecnologia MIMO massiva.

Abstract: This letter proposes an adaptive beamforming switch algorithm for realistic massive multiple-input multiple-output (MIMO) systems through prototypes. It is analyzed and identified that a rigid single-mode beamforming regime is hard to maintain superior performance all the time due to no adaption to the inevitable channel variation in practice. In order to cope with this practical issue, the proposed systematic beamforming mechanism is investigated to enable dynamic selection between minimum mean-squared error and grid-of-beams beamforming algorithms, which improves system downlink performance, including throughput and block error rate. The significant performance benefits and realistic feasibility have been validated through the field tests in live networks and theoretical analyses. Meanwhile, the adaptive beamforming switch algorithm is applicable to both fourth and fifth generation time-division duplexing cellular communication system using massive-MIMO technology.
