Abstract

This paper investigates the construction of QAM Golay complementary sequence pairs (CSPs) based on standard binary Golay–Davis–Jedwab (GDJ) CSPs. In order to guarantee that the proposed construction produces QAM Golay CSPs, a sufficient condition that the coefficients of offsets should satisfy is developed, which is fit for finding all the coefficients by a computer. In particular, all the coefficients of offsets over the 64- and 256-QAM constellations are given. The proposed construction includes Zeng’s and Ma et al.’s ones as special cases. The inputs of resultant sequence pairs are binary signals rather than quaternary ones, which means that the resulting sequences are fit for such QAM systems that merely depend on binary inputs. The obtained QAM Golay CSPs can be applied to orthogonal frequency division multiplexing systems so as to reduce peak envelope power of their signals.

一般QAM互补序列对的一个充分条件

本文研究了基于标准二进制Golay - davis - jedwab (GDJ)互补序列对的QAM Golay互补序列对(csp)的构建。为了保证所提出的结构产生QAM Golay csp，给出了偏移系数应满足的充分条件，该条件适合于用计算机求出所有的偏移系数。特别地，给出了64- qam和256-QAM星座上的所有偏移系数。本文提出的结构包括Zeng和Ma等人的结构作为特例。结果序列对的输入是二进制信号而不是四元信号，这意味着结果序列适合于仅依赖二进制输入的QAM系统。所得到的QAM Golay csp可以应用于正交频分复用系统，以降低其信号的峰值包络功率。
