准互补序列集（QCSS）可以看作是完全互补码（CCC）的一种推广形式，它使多载波通信系统能够支持更多的用户。这项工作的贡献是双重的。首先，我们提出了一个系统的建设佛罗伦萨矩形。其次，我们提出了几套CCC和QCSS，使用佛罗伦萨矩形。CCC和QCSS是在$\mathbb {Z}_{N}$上构造的，其中$N\geq 2$是任意整数。所构造的CCC中的任何两个的互相关幅度的上界为$N$。通过结合建议的CCC，我们提出了渐近最优和接近最优的QCSS与新的参数。
Quasi-complementary sequence sets (QCSSs) can be seen as a generalized version of complete complementary codes (CCCs), which enables multicarrier communication systems to support more users. The contribution of this work is two-fold. First, we propose a systematic construction of Florentine rectangles. Secondly, we propose several sets of CCCs and QCSSs, using Florentine rectangles. The CCCs and QCSSs are constructed over $\mathbb {Z}_{N}$ , where $N\geq 2$ is any integer. The cross-correlation magnitude of any two of the constructed CCCs is upper bounded by $N$ . By combining the proposed CCCs, we propose asymptotically optimal and near-optimal QCSSs with new parameters.
