摘要:

零相关区(ZCZ)序列和Golay序列是两种具有不同相关特性的序列。Gong \textit{et al.}和Chen \textit{et al.}指出,一些Golay序列也具有大的ZCZ,并且是OFDM系统中导频的良好候选。文献中报道的具有ZCZ的已知Golay序列在长度上具有2的幂形式的限制。本文的一个目的是提出一种新的长度的Golay互补对(GCPs)的周期自相关的Golay序列和周期互相关的对显示零相关区(ZCZ)周围的同相位置的建设。具体地,所提出的GCP具有长度$4N$(其中,$N$是GCP的长度)和ZCZ宽度$N+1$。本文的另一个目的是将构造扩展到二维Golay互补阵列偶(GCAP)。有趣的是,所提出的GACP的周期性互相关在同相位置周围也具有大的ZCZ。

英文摘要:

Zero correlation zone (ZCZ) sequences and Golay sequences are two kinds of sequences with different preferable correlation properties. It was shown by Gong \textit{et al.} and Chen \textit{et al.} that some Golay sequences also possess a large ZCZ and are good candidates for pilots in OFDM systems. Known Golay sequences with ZCZ reported in the literature have a limitation in the length which is the form of a power of 2. One objective of this paper is to propose a construction of Golay complementary pairs (GCPs) with new lengths whose periodic autocorrelation of each of the Golay sequences and periodic corss-correlation of the pair displays a zero correlation zone (ZCZ) around the in-phase position. Specifically, the proposed GCPs have length $4N$ (where, $N$ is the length of a GCP) and ZCZ width $N+1$. Another objective of this paper is to extend the construction to two-dimensional Golay complementary array pairs (GCAPs). Interestingly the periodic corss-correlation of the proposed GACPs also have large ZCZs around the in-phase position.
