The contributions of this article are twofold: Firstly, we introduce a novel class of sequence pairs, called “cross Z-complementary pairs (CZCPs),” each displaying zero-correlation zone (ZCZ) properties for both their aperiodic autocorrelation sums and crosscorrelation sums. Systematic constructions of perfect CZCPs based on selected Golay complementary pairs (GCPs) are presented. Secondly, we point out that CZCPs can be utilized as a key component in designing training sequences for broadband spatial modulation (SM) systems. We show that our proposed SM training sequences derived from CZCPs lead to optimal channel estimation performance over frequency-selective channels.

用于频率选择性信道上空间调制最佳训练的交叉 Z 互补对


本文的贡献是双重的：首先，我们引入了一类新颖的序列对，称为“交叉 Z 互补对 (CZCP)”，每个序列对的非周期自相关和和互相关和都显示零相关区 (ZCZ) 属性。提出了基于选定的 Golay 互补对 (GCP) 的完美 CZCP 的系统构建。其次，我们指出 CZCP 可以用作设计宽带空间调制（SM）系统训练序列的关键组件。我们表明，我们提出的从 CZCP 导出的 SM 训练序列可以在频率选择性信道上实现最佳信道估计性能。
