초록

본 본문에서는 Code division multiple access (CDMA) 사용자와 협대역 사용자가 동일 주파수 대역에 존재하는 곳에서 direct sequence/CDMA (DS/CDMA) 오버레이 시스템에 대해 pseudorandom noise (PN) 코드 획득 성능 상의 안테나 다이버시티의 효과가 분석되고 시뮬레이션 되었다. 시뮬레이션 결과는 안테나 다이버시티가 PN 획득 성능에 매우 효과적임을 보인다. 이 논문의 결과는 DS/CDMA 오버레이 환경에서 동기 구조의 설계에 적용될 수 있다.

In this paper, effect of antenna diversity on pseudorandom noise (PN) code acquisition performance is analyzed and simulated for a direct sequence/code division multiple access (DS/CDMA) overlay system where a CDMA user and a narrowband user coexist in the same frequency band. From the simulation results, it is shown that the antenna diversity is very effective in improving the PN acquisition performance. The results of this paper can be applied to design of synchronization scheme for a DS/CDMA overlay environment.
