Constructions of Quaternary Periodic Complementary Sequence Sets with Zero Correlation Zone
-
摘要: 该文分别基于二元零相关区周期互补序列集和二元周期互补序列集做为初始序列,利用逆Gray映射构造了四元零相关区周期互补序列集。如果选取的初始序列集参数可以达到理论界限,得到的四元零相关区周期互补序列集接近甚至达到理论界限。零相关区互补序列集相比传统互补序列集具有更多的序列数目,应用到通信系统中可以支持更多的通信用户。Abstract: Based on binary periodic complementary sequence set and binary Zero-Correlation Zone (ZCZ) sequence set, constructions of quaternary periodic complementary sequence sets with zero-correlation zone are proposed by using the inverse Gray mapping. If the initial sequence set is optimal, then the resultant quaternary ZCZ periodic complementary set is optimal or almost optimal with respect to the theoretical bound. ZCZ periodic complementary sets have larger set size compared with the conventional complementary sets, and can support more users in communication systems.
