초록

ZCZ(Zero Cross-correlation Zone) 부호(code)는 다중 사용자 CDMA 시스템에서 낮은 상관 영역(low correlation zone) 제공하고 상호 채널간섭(co-channel interference)을 제거하는 좋은 성능을 보이고 있다. 본 논문에서는 복소 확산기술(complex spreading scheme)을 이용해 이와 같은 상관관계의 성질을 갖는 확산 부호설계(spreading code design)를 분석하고 그들의 효율성을 이동통신시스템에 적용한다. 또한 자켓 다위상 비트열(Jacket polyphase sequence)을 예로 들어 개선된 성능과 일반 성질을 제시했다.

Zero Cross-correlation Zone (ZCZ) code has a good performance in Multi-user CDMA system to get low correlation zone and reject co-channel interference. In this paper, we do analysis of spreading code design to obtain this kind of property of correlations with a complex spreading scheme and denote their effective performance for mobile communication system. In addition, a Jacket polyphase sequence is an example to show the improved performance and regular properties effective performance for mobile communication system. In addition, a Jacket polyphase sequence is as an example to show the improved performance and regular properties.
