广义Reed-Muller码的最优Z-互补码集

Optimal Z-complementary Code Set From Generalized Reed-Muller Codes

Palash Sarkar, Sudhan Majhi, Zilong Liu

摘要:

Z-互补码集(ZCCS)是完美互补码(CC)的一种扩展,是指具有零相关区特性的二维矩阵的集合。ZCCS可用于各种多信道系统中以支持例如准同步无干扰多载波码分多址通信和多输入多输出系统中的最优信道估计。传统的ZCCS结构严重依赖于一系列的序列操作,这对于快速的硬件生成来说可能是不可行的,特别是对于长ZCCS。在本文中,我们提出了一个直接建设ZCCS使用二阶Reed-Muller码与有效的图形表示。我们提出的建设,有效的任何数量的孤立的顶点存在于图中,是能够产生最佳的ZCCS满足集大小上界。

英文摘要:

Z-complementary code set (ZCCS), an extension of perfect complementary codes (CCs), refers to a set of two-dimensional matrices having zero correlation zone properties. ZCCS can be used in various multi-channel systems to support, for example, quasi-synchronous interference-free multicarrier code-division multiple access communication and optimal channel estimation in multiple-input multiple-output systems. Traditional constructions of ZCCS heavily rely on a series of sequence operations which may not be feasible for rapid hardware generation particularly for long ZCCSs. In this paper, we propose a direct construction of ZCCS using second-order Reed-Muller codes with efficient graphical representation. Our proposed construction, valid for any number of isolated vertices present in the graph, is capable of generating optimal ZCCS meeting the set size upper bound.
