공간 영역에서 CCI를 억제하려면 적응형 배열 안테나를 적용해야 합니다. 그러나 적응형 배열 안테나는 다음과 같은 몇 가지 문제점을 갖고 있다. 적응형 배열 안테나는 최적의 안테나 가중치로 수렴하는 데 오랜 시간이 걸리기 때문에 채널이 빠르게 변하는 경우 추적이 어렵습니다. 반면, 배열 안테나의 소자 수에 따라 처리 부담이 증가한다. 이러한 문제를 해결하기 위해 우리는 배열 안테나를 요소 안테나로 사용하는 적응형 배열 안테나, 소위 "계층형 배열 안테나"를 제안한다. 첫 번째 레이어에서는 섹터 영역이 정의됩니다. 섹터 영역은 안테나 가중치에 의해 정의되므로 DOA 분포에 따라 섹터 영역을 변경할 수 있습니다. 두 번째 계층에서는 MMSE가 수행됩니다. 첫 번째 레이어에서 억제할 수 없었던 간섭은 두 번째 레이어에서 억제됩니다. 제안한 시스템을 통해 처리 복잡성을 완화하면서 더 높은 수렴 속도를 확인했습니다.

Abstract: An adaptive array antenna should be applied for suppression of CCI in the spatial domain. However, the adaptive array antenna has some problems as follows. Because the adaptive array antenna takes a long time to converge to the optimum antenna weights, it's hard to track in case of quick varying channel. On the other hand, processing burden increases with the number of elements in the array antenna. To solve these problems, we propose an adaptive array antenna using array antenna as element antennas, the so-called "Layered array antenna." At the 1st layer, sector area are defined. We can change the sector areas according to the DOA distribution, because the sector areas are defined by the antenna weights. At the 2nd layer, MMSE is performed. Interference that couldn't be suppressed at the 1st layer is suppressed at the 2nd layer. By the proposed system, we confirmed higher convergence speed while relieving processing complexity.
