A-ZCZ(Asymmetric Zero Correlation Zone) 시퀀스 세트는 여러 시퀀스 하위 세트로 구성된 특별한 유형의 ZCZ 시퀀스 세트로 간주될 수 있습니다. 각 하위 집합은 ZCZ 시퀀스 집합이며, 서로 다른 하위 집합의 시퀀스 간에 공통 ZCCZ(Zero Cross-Correlation Zone)를 갖습니다. 이 논문은 A-ZCZ 시퀀스 세트의 기존 구성을 보완하고 연구 결과를 더욱 향상시킵니다. 게다가 행렬 변환을 통해 A-ZCZ 시퀀스 세트의 새로운 구성이 제안되었습니다. 획득된 시퀀스 세트는 이론적 경계와 관련하여 최적이며, 하위 세트 수 및 서로 다른 하위 세트의 시퀀스 간 ZCCZ 길이와 같은 매개 변수를 보다 유연하게 선택할 수 있습니다. 또한, 직교행렬의 다양성과 초기행렬의 유연성으로 인해 더 많은 A-ZCZ 시퀀스 집합을 얻을 수 있다. 본 논문에서 제시된 결과 시퀀스 세트는 다중 셀 QS-CDMA(quasi-synchronous code-division multiple-access) 시스템에 적용되어 동일한 셀뿐만 아니라 인접 셀로부터의 간섭을 제거할 수 있습니다.

Abstract: An asymmetric zero correlation zone (A-ZCZ) sequence set can be regarded as a special type of ZCZ sequence set, which consists of multiple sequence subsets. Each subset is a ZCZ sequence set, and have a common zero cross-correlation zone (ZCCZ) between sequences from different subsets. This paper supplements an existing construction of A-ZCZ sequence sets and further improves the research results. Besides, a new construction of A-ZCZ sequence sets is proposed by matrices transformation. The obtained sequence sets are optimal with respect to theoretical bound, and the parameters can be chosen more flexibly, such as the number of subsets and the lengths of ZCCZ between sequences from different subsets. Moreover, as the diversity of the orthogonal matrices and the flexibility of initial matrix, more A-ZCZ sequence sets can be obtained. The resultant sequence sets presented in this paper can be applied to multi-cell quasi-synchronous code-division multiple-access (QS-CDMA) systems, to eliminate the interference not only from the same cell but also from adjacent cells.

AB - An asymmetric zero correlation zone (A-ZCZ) sequence set can be regarded as a special type of ZCZ sequence set, which consists of multiple sequence subsets. Each subset is a ZCZ sequence set, and have a common zero cross-correlation zone (ZCCZ) between sequences from different subsets. This paper supplements an existing construction of A-ZCZ sequence sets and further improves the research results. Besides, a new construction of A-ZCZ sequence sets is proposed by matrices transformation. The obtained sequence sets are optimal with respect to theoretical bound, and the parameters can be chosen more flexibly, such as the number of subsets and the lengths of ZCCZ between sequences from different subsets. Moreover, as the diversity of the orthogonal matrices and the flexibility of initial matrix, more A-ZCZ sequence sets can be obtained. The resultant sequence sets presented in this paper can be applied to multi-cell quasi-synchronous code-division multiple-access (QS-CDMA) systems, to eliminate the interference not only from the same cell but also from adjacent cells.
