본 논문에서는 Evolved UTRA 하향링크에서 최적의 SCH 구조를 설정하기 위해 초기 셀 검색 시간과 인접 셀 검색 시간 측면에서 계층적 및 비계층적 SCH(동기화 채널) 구조를 비교합니다. 컴퓨터 시뮬레이션 결과, 19-셀 구성에서 계층적 SCH 구조를 사용한 누적 분포 함수(CDF)에서 90%의 셀 검색 시간은 인접 셀 검색에서 비계층적 SCH 구조를 사용한 것보다 절반 미만인 것으로 나타났습니다. 낮은 신호 대 간섭 + 잡음 전력비(SINR) 조건. 두 구조 모두 초기 셀 검색에서 거의 동일한 셀 검색 시간을 달성합니다. 이는 계층적 SCH 구조의 상호상관 기반 SCH 심볼 타이밍 검출에 기인하며, 이는 비계층적 SCH 구조의 자기상관 기반 검출에 비해 잡음의 영향을 덜 받는다. 따라서, 특히 인접 셀 검색에서 셀 검색 시간 성능을 기반으로 계층적 SCH 구조가 비계층적 SCH 구조보다 우수하다는 결론을 내렸습니다.

Abstract: This paper presents a comparison of hierarchical and non-hierarchical synchronization channel (SCH) structures in terms of the initial cell search time and neighboring cell search time in order to establish the optimum SCH structure in the Evolved UTRA downlink. Computer simulation results show that in a 19-cell configuration, the cell search time at 90% in the cumulative distribution function (CDF) using the hierarchical SCH structure is less than half that using the non-hierarchical SCH structure in a neighboring cell search under low signal-to-interference plus noise power ratio (SINR) conditions, although both structures achieve almost the same cell search time in the initial cell search. This is due to the cross-correlation based SCH symbol timing detection in the hierarchical SCH structure, which is affected less by noise than the auto-correlation based detection in the non-hierarchical SCH structure. Thus, we conclude that the hierarchical SCH structure is superior to the non-hierarchical SCH structure based on the cell search time performance especially in the neighboring cell search.
