具有良好相关特性的序列的设计由于其在不同技术领域的应用而在信号处理中长期受到关注。这种序列的计算构造通常依赖于积分旁瓣电平（ISL）相关度量的最小化，该度量有效地降低了异相滞后的相关幅度。在本文中，我们解决了在零相关区具有良好的互相关和互补互相关特性的幺模序列集的设计。数值结果表明，所产生的序列在识别严格线性（SL）和广泛线性（WL）系统的潜力。
The design of sequences with good correlation properties has been of long-standing interest in signal processing owing to their applications in diverse fields of technology. The computational construction of such sequences typically relies on the minimization of Integrated Sidelobe Level (ISL)-related metrics that effectively lower the correlation magnitude for out-of-phase lags. In this paper, we address the design of sets of unimodular sequences with good cross-correlation and complementary cross-correlation properties over a zero-correlation-zone. Numerical results show the potential of the generated sequences in identifying both strictly linear (SL) and widely linear (WL) systems.
