Un ensemble de séquences de zone de corrélation nulle asymétrique (A-ZCZ) peut être considéré comme un type spécial d’ensemble de séquences ZCZ, composé de plusieurs sous-ensembles de séquences. Chaque sous-ensemble est un ensemble de séquences ZCZ et possède une zone de corrélation croisée nulle commune (ZCCZ) entre les séquences de différents sous-ensembles. Cet article complète une construction existante d’ensembles de séquences A-ZCZ et améliore encore les résultats de la recherche. Par ailleurs, une nouvelle construction d’ensembles de séquences A-ZCZ est proposée par transformation matricielle. Les ensembles de séquences obtenus sont optimaux par rapport à la limite théorique et les paramètres peuvent être choisis de manière plus flexible, tels que le nombre de sous-ensembles et les longueurs de ZCCZ entre les séquences de différents sous-ensembles. De plus, grâce à la diversité des matrices orthogonales et à la flexibilité de la matrice initiale, davantage d’ensembles de séquences A-ZCZ peuvent être obtenus. Les ensembles de séquences résultants présentés dans cet article peuvent être appliqués à des systèmes multicellulaires à accès multiple par répartition en code quasi-synchrone (QS-CDMA), pour éliminer les interférences non seulement de la même cellule mais également des cellules adjacentes.

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.
