在下一代CDMA无线通信系统中，利用互补序列可以实现无多址干扰（MAI）和多径干扰（MPI）的理想传输，从而大大提高系统的性能。Z-互补序列扩展了互补序列。基于零相关区序列，提出了一种新的Z-互补序列的构造方法。通过选取不同的参数N值，可以在ZCZ宽度、Z-互补序列的子序列个数和长度之间进行折衷，以适应不同的应用场景。
The ideal transmission without multiple access interference (MAI) and multi-path interference (MPI) can be achieved in the next-generation CDMA wireless communication system by using complementary sequences, which can greatly improve the performance of such a system. Z-complementary sequences extend complementary sequences. In this paper, based on zero correlation zone (ZCZ) sequences, a new construction of Z-complementary sequences is presented. The trade-off among the width of ZCZ, the number and the length of sub-sequences of Z-complementary sequences can be made by choosing different values of parameter N, which will be suitable for various applied scenes.
