本文提出了一种广义正交Golay互补序列(OGCS)集,它由多个子集组成,每个子集都是一个常规的OGCS集,不同子集中的任意两个序列具有三值低同相互相关(IPCC)。以IPCC性能略有下降为代价,我们集合中的序列数量大大增加。将该序列集应用于正交频分复用调制的高频多进制扩频通信链路中,可将发射信号的峰均包络功率比控制在不超过3dB,并可获得比现有序列集更高的数据速率。最后,仿真结果表明,在误码率和频谱效率之间的理想的折衷。
In this letter, we present a generalized orthogonal Golay complementary sequence (OGCS) set that consists of multiple subsets, therein, each subset is a conventional OGCS set, and any two sequences from different subsets have three-valued low in-phase cross-correlation (IPCC). At the cost of slight reduction of IPCC performance, the number of sequences in our set is enormously enlarged. When our set is applied to high frequency M-ary spread spectrum communication link with orthogonal frequency division multiplexing modulation, the peak-to-mean envelope power ratio of the transmitted signal can be controlled not to exceed 3 dB, and the data rate can be higher than the one from the existing sequence sets. Finally, the simulation results show a desirable tradeoff between bit error rate and spectral efficiency.
