본 논문에서는 실내 패킷 통신 시스템에서 직접 시퀀스 확산 스펙트럼 신호의 코드 획득을 위한 매크로/마이크로 다이버시티 기법을 연구한다. 논의된 시스템에서 기지국에는 각각 안테나 클러스터가 있는 여러 개의 무선 포트가 있고 단말기에도 여러 개의 안테나가 있습니다. 이 시스템의 업링크 성능은 로그노멀 섀도잉(Lognormal Shadowing)과 플랫 레일리 페이딩(Flat Rayleigh Fading)으로 분석됩니다. 수치 결과는 제안된 다양성 기법에 의해 성능이 크게 향상되었음을 보여줍니다. 또한, 성능 척도로 자주 사용되는 평균 획득 시간은 초기 코드 획득에 필요한 프리앰블 길이를 과소평가하므로 패킷 무선 시스템에 적합하지 않다는 것이 명확해졌습니다.

Abstract: In this paper, we study macro/micro diversity techniques for code acquisition of a direct-sequence spread-spectrum signal in an indoor packet communication system. In the system discussed, the base station has several radio ports each with a cluster of antennas, and the terminal also has multiple antennas. The performance in the uplink of this system is analyzed under Lognormal shadowing and flat Rayleigh fading. The numerical results show great performance improvements by proposed diversity techniques. In addition, it is clarified that the mean acquisition time, which is often used as the measure of performance, is not suitable for packet radio systems as it underestimates the necessary preamble length for initial code acquisition.
