초록

분산 다중 안테나 기반의 상호협력 통신(cooperative MIMO)을 구현하기 위해 대역 효율성 있는 두 가지 방식의 상호협력 전송 프로토콜을 제안하고 비교 분석한다. 같은 시분할 슬롯에 전송된 모든 심볼들 간에 간섭이 없다고 가정한 경우에 대해 각 전송 프로토콜의 BER 성능을 AF (Amplify-and-Forward)와 DF (Decode-and-Forward) 방식에서 각각 분석한다. 수학적 분석과 모의실험 결과를 통해 제안한 전송 방식이 직접 전송 방식(direct transmission)에 비해 대역폭을 추가로 사용하지 않고 많은 이득이 있음을 보여준다.

In this paper, we propose two different types of cooperative transmission protocols, referred to as spatial multiplexing with receive diversity (SMRD), that are bandwidth-efficient. We show that the BER performance can be significantly improved with a proper design of SMRD protocol under the AF (Amplify-and-Forward) and the DF (Decode-and-Forward) modes of relaying, when there is no interference among all symbols transmitted in the same time slot. BER analysis and our simulation result show that the proposed transmission protocol achieves a significant gain over no-cooperation (direct transmission) without any bandwidth expansion.
