본 논문은 다중 셀 상향링크 시스템의 셀 간 간섭을 완화시키기 위한 부분공간 간섭 정렬을 적용했을 때 높은 채널 이득과높은 합용량을 얻기 위해 간섭 신호공간 형성에 사용되는 레퍼런스 벡터 설정 방법을 제안하였다. 제안된 방법은 레퍼런스 벡터의 설정에 따라 채널과의 매칭이 달라지고 이로부터 셀의 합용량이 변화하는 레퍼런스 벡터의 다이버서티를 얻는 것이다. 각 셀의 처리량을 최대화시키기 위해 전송 전에 여러 개의 레퍼런스 벡터를 전송하고 이중에서 최적의 레퍼런스 벡터를 선정함으로써 기존의 간섭정렬방식보다 높은 채널 이득과 높은 합용량을 얻을 수 있다. 전산 모의실험을 통해 제안된 방법을 적용한 경우 임의로 설정된 레퍼런스 벡터를 설정했을 때의 셀 합용량에 비해 약 60% 향상된 값을 얻었다.
