우리는 다양한 방식의 기지국/라우터-릴레이-사용자 전송과 같은 다운링크 협력 MIMO 통신에서 재생 및 비재생 중계 단말의 활용을 조사하고 제안합니다. 소스에는 다중 안테나가 장착되어 있고, 릴레이와 대상에는 단일 안테나 터미널이 있습니다. 소스에서 릴레이로 심볼은 MIMO 공간 다중화 기술을 사용하여 전송됩니다. 중계 방식의 유형에 따라 중계기는 수신된 신호를 완전히 디코딩하거나 증폭한 후 단순 TDM 전송 또는 Alamouti의 시공간 코딩을 사용하여 대상으로 재전송합니다. 제안한 시스템은 단일 안테나 시스템 환경에서 MIMO 성능을 구현하며, 특히 낮은 SNR 조건에서 기존 전송 방식보다 성능면에서 우수함을 보여줍니다. 또한, 제안된 시스템은 다음과 같은 다양성 차수를 제공하는 것으로 나타났습니다. N-M+1, MIMO V-BLAST 시스템과 유사합니다.

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.
