초록

본 논문에서는 다중안테나 single carrier frequency division multiple access (SC-FDMA) 시스템의 채널 이득 행렬 구조를 활용한 새로운 신호검출기법을 제안한다. 제안된 기법은 큰 채널이득 행렬을 여러 개의 작은 행렬로 근사화 할 수 있다는 점과 작은 행렬에 격자감소기술을 효과적으로 적용할 수 있다는 점을 활용한다. 모의실험을 통해 제안된 기법의 개선된 성능을 확인한다.

In this paper, we address data detection technique using Fixed complexity LLL-based signal detection over multi-antenna SC-FDMA wireless channels. We use the property of effective channel matrix of SC-FDMA system. We can make the large effective channel matrix to various small effective channel matrix. We show that error performance of proposed detection technique.
