Investigamos e propomos a utilização de terminais de retransmissão regenerativos e não regenerativos em comunicações MIMO cooperativas de downlink, como na transmissão de estação base/roteador-retransmissor-usuário sob diferentes esquemas. A fonte é equipada com múltiplas antenas, enquanto os relés e o destino são terminais de antena única. Da fonte aos relés, os símbolos são transmitidos usando a técnica de multiplexação espacial MIMO. Dependendo do tipo de esquema de retransmissão, os relés decodificam totalmente ou amplificam o sinal recebido antes de retransmiti-lo ao destino usando transmissão TDM simples ou codificação espaço-tempo de Alamouti. Mostramos que o sistema proposto alcança desempenho MIMO em ambiente de sistema de antena única e, em termos de desempenho, é superior aos esquemas de transmissão existentes, especialmente em condições de baixo SNR. Além disso, o sistema proposto mostra uma ordem de diversidade de N-M+1, semelhante ao sistema MIMO V-BLAST.

Abstract: We investigate and propose the utilization of regenerative and non-regenerative relaying terminals in downlink cooperative MIMO communications, such as in base-station/router-relay-user transmission under different schemes. The source is equipped with multiple antennas, while the relays and destination are single-antenna terminals. From the source to the relays, symbols are transmitted using MIMO spatial-multiplexing technique. Depending on the type of relaying scheme, the relays either fully decode or amplify the received signal before retransmitting it to the destination using simple TDM transmission or Alamouti's space-time coding. We show that the proposed system realizes MIMO performance in single-antenna system environment, and performance-wise it is superior to existing transmission schemes, especially in low-SNR conditions. Furthermore, the proposed system is shown to give a diversity order of N-M+1, similar to that of MIMO V-BLAST system.
