Abstract

다중 송수신 노드를 갖는 무선 시스템에서의 간섭 제어 방법이 개시된다. 다중 송수신 노드를 갖는 무선 시스템에서의 간섭 제어 방법은 복수의 수신 노드들이 서로의 채널 정보를 공유하고, 각 수신 노드가 공유된 채널정보를 이용하여 프리코딩 행렬을 계산하여 송신 노드로 피드백하고, 각 송신노드는 상기 피드백받은 각자의 프리코딩 행렬을 이용하여 송신 신호를 수신 노드로 전송함으로써 간섭을 제어한다. 수신 노드들 사이에 채널정보를 공유하는 것만으로도 완벽한 간섭정렬을 할 수 있고, 셀간 간섭뿐 아니라 셀내 간섭 환경에서도 적용할 수 있다.
