Abstract

This paper proposes the acquisition system using the multiple antennas in DS-CDMA system. The conventional acquisition schemes using multiple antennas are the methods to utilize the multi-antenna combining and the fixed multi-beam forming of a serial acquisition. Then, this paper proposes the hybrid acquisition scheme using the fixed multi-beam forming. The numerical results show the performance comparison of two acquisition schemes in terms of the acquisition time ill the multipath Rayleigh fading channel.

본 논문에서는 DS CDMA 시스템에서 다중안테나를 이용한 옹기획득 시스템을 제안하고 있다 기존의 다중안테나를 이용한 옹기획득 방식은 다중안테나 결항을 이용한 방법과 고정 다중빔 형성을 이용한 직렬동기획득방식 등이 있다. 그런데, 본 논문에서는 고정 다중빔 형성을 이용한 히이브리드 동기획득 방식을 제안하고 있다. 수치 해석 결과로는 다경로 Raylelgh 페이딩 채널에서 옹기획득시간 측면에서 두 방식에 대한 동기획득 성능을 비교하고 있다.
