几乎最优二元多子集零相关区序列集构造法

摘要

Multiple Zero Correlation Zone (ZCZ) sequence sets are sutilable to Quasi-Synchronous Code-Division Multiple-Access (QS_CDMA) systems to remove both the Multi-Path Interference (MPI) and the Inter-Cell Interference (ICI).In this paper,multiple binary ZCZ sequence sets with inter-set Zero Corss-Correlation Zone (ZCCZ) are constructed from aperiodic complementary sequence sets with ZCZ,the resultant binary ZCZ sequence sets are almost optimal.%多子集零相关区序列集适用于多小区环境下的准同步码分多址系统,可以同时消除小区内用户间干扰和小区间用户干扰.该文利用零相关区非周期互补序列集构造了参数几乎最优的二元多子集零相关区序列集.
