Um conjunto de sequências de zona de correlação zero assimétrica (A-ZCZ) pode ser considerado como um tipo especial de conjunto de sequências ZCZ, que consiste em múltiplos subconjuntos de sequências. Cada subconjunto é um conjunto de sequências ZCZ e possui uma zona de correlação cruzada zero comum (ZCCZ) entre sequências de diferentes subconjuntos. Este artigo complementa uma construção existente de conjuntos de sequências A-ZCZ e melhora ainda mais os resultados da pesquisa. Além disso, uma nova construção de conjuntos de sequências A-ZCZ é proposta por transformação de matrizes. Os conjuntos de sequências obtidos são ótimos em relação ao limite teórico e os parâmetros podem ser escolhidos de forma mais flexível, como o número de subconjuntos e os comprimentos de ZCCZ entre sequências de diferentes subconjuntos. Além disso, conforme a diversidade das matrizes ortogonais e a flexibilidade da matriz inicial, mais conjuntos de sequências A-ZCZ podem ser obtidos. Os conjuntos de sequências resultantes apresentados neste artigo podem ser aplicados a sistemas multicelulares de acesso múltiplo por divisão de código quase síncrono (QS-CDMA), para eliminar a interferência não apenas da mesma célula, mas também de células 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.

Each subset is a ZCZ sequence set, and have a common zero cross-correlation zone (ZCCZ) between sequences from different subsets.
