Abstract

In this paper, we analysis the end-to-end performance of the incremental cooperative communication with relay selection. In the conventional cooperative scheme, the source(S) broadcasts the signal to the relay(R) and the destination(D) at 1st phase, and the R forwards the signal to the D at 2nd phase. Although this scheme can improve performance and provide diversity gain, it suffers from decreasing spectrum efficiency. In order to overcome this problem, the incremental cooperative model can be used. In this paper, we study two incremental cooperative method : the first uses ARQ with threshold SNR and the second uses HARQ with channel coding. we also evaluated performance of the incremental cooperative communication based on the R arrangement by using both methods.

본 논문에서는 중계기 선택 기법이 적용된 증분 협력 통신의 단-대-단 성능을 분석한다. 일반적인 협력 통신은 1 phase에 송신단(S)에서 전송하는 신호를 수신단(D)이 한 번 수신하고, 2 phase에 중계기(R)로부터 S에서 전송한 신호를 재 전송받게 된다. 이러한 과정을 통해 D는 다이버시티 이득을 얻음으로써 수신 성능이 향상되지만, 두 번에 걸친 전송은 스펙트럼 효율성을 감소시킨다. 하지만 증분형 중계 기법을 적용한 협력 통신에서 D는 1 phase에 수신한 신호만으로 복호에 성공할 수 있다고 판단되면, 두 번째 전송을 생략함으로써 이러한 단점을 보완할 수 있다. 증분형 중계 기법에서 D는 ACK/NACK 메시지를 전송하는 ARQ(Automatic Repeat reQuest) 기법을 이용한다. 본 논문에서는 D가 첫 번째 시간 슬롯에 수신한 신호를 복호할 수 있는지를 판단하기 위해 임계 SNR을 이용한 ARQ 기법과 채널 부호화를 이용한 HARQ(Hybrid Automatic Repeat reQuest) 기법과 같이 두 가지 방법을 고려한 시스템에 참여하는 중계기 배치에 따른 성능을 분석하고, 중계기 배치가 성능에 미치는 영향에 대해 연구한다.
