Neste artigo, o canal de retransmissão multiusuário de múltiplas entradas e saídas (MU-MIMO) é investigado, onde o nó de origem fornece multifeixes para multiusuários por meio de um nó de retransmissão com múltiplas antenas. Neste cenário, a matriz de processamento linear no nó de retransmissão é projetada em torno do esquema diagonal de bloco (BD) para melhorar a taxa de soma do sistema. Comparada com a matriz de processamento linear tradicional com esquema de força zero (ZF) no nó de relé, a matriz proposta baseada no esquema BD pode não apenas eliminar a interferência multiusuário na mesma medida que o esquema ZF, mas também obter potência ideal alocação no nó de retransmissão. Simulações numéricas demonstram que o esquema BD supera o esquema ZF e pode melhorar significativamente o desempenho da taxa de soma.

Abstract: In this paper, the multi-user multiple-input multiple-output (MU-MIMO) relay channel is investigated, where the source node provides multi-beams to multi-users via a multi-antenna relay node. In this scenario, linear processing matrix at the relay node is designed around block diagonal (BD) scheme to improve the system sum-rate. Compared with the traditional linear processing matrix with zero-forcing (ZF) scheme at the relay node, the proposed matrix based on BD scheme can not only eliminate the multi-user interference to the same extent as the ZF scheme, but also realize optimal power allocation at the relay node. Numerical simulations demonstrate the BD scheme outperforms the ZF scheme and can significantly improve the sum-rate performance.
