Abstract

In this paper, a selective multiple-input multiple-output(MIMO) transmission scheme is proposed in dual-hop MIMO relaying systems, in which orthogonal space-time block code(OSTBC) transmission and transmit antenna selection(TxAS) transmission are selectively used. Assuming independent Rayleigh fading channels, the outage probability is analyzed for a decode-and-forward(DF) relaying system using the selective MIMO transmission scheme. Also, through numerical investigation, the outage performance for the DF relaying system using the selective MIMO transmission scheme is compared with that for the conventional DF relaying system using OSTBC or TxAS. Moreover, from the performance comparison, it is shown that the proposed scheme can reduce the system overhead without outage performance degradation.

본 논문에서는 듀얼 홉 multiple-input multiple-output(MIMO) 중계 시스템에서 직교시공간블록코드 전송과 송신안테나 선택 전송을 선택적으로 이용하는 선택적 MIMO 전송 기술을 제안한다. 독립적인 레일레이 페이딩 채널을 가정하여 선택적 MIMO 전송 기술 기반의 디코딩 후 전달 중계 시스템에 대한 아웃티지 확률을 분석하고, 수치적 결과를 통해 직교시공간블록코드 전송 또는 송신안테나 선택 전송을 모든 홉에서 동일하게 이용하는 기존 시스템과 아웃티지 성능을 비교한다. 또한, 성능 비교를 통해 제안 기술이 아웃티지 성능의 저하 없이 시스템 오버헤드를 감소시킬 수 있음을 보인다.
