Set jujukan zon korelasi sifar (A-ZCZ) asimetri boleh dianggap sebagai jenis set jujukan ZCZ khas, yang terdiri daripada berbilang subset jujukan. Setiap subset ialah set jujukan ZCZ, dan mempunyai zon korelasi silang sifar biasa (ZCCZ) antara jujukan daripada subset berbeza. Kertas kerja ini menambah pembinaan set jujukan A-ZCZ sedia ada dan menambah baik lagi hasil penyelidikan. Selain itu, pembinaan baharu set jujukan A-ZCZ dicadangkan oleh penjelmaan matriks. Set jujukan yang diperoleh adalah optimum berkenaan dengan terikat teori, dan parameter boleh dipilih dengan lebih fleksibel, seperti bilangan subset dan panjang ZCCZ antara jujukan daripada subset yang berbeza. Selain itu, kerana kepelbagaian matriks ortogon dan fleksibiliti matriks awal, lebih banyak set jujukan A-ZCZ boleh diperolehi. Set jujukan terhasil yang dibentangkan dalam kertas ini boleh digunakan pada sistem berbilang akses pembahagian kod kuasi segerak (QS-CDMA) berbilang sel, untuk menghapuskan gangguan bukan sahaja daripada sel yang sama tetapi juga daripada sel bersebelahan.

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.
