| 摘 要： | 基于自相关理想序列和正交矩阵建立一类统一的具有零(低)相关区的扩频序列构造方法,并对其相关特性进行分析和证明。该类方法可通过序列和矩阵的任意选取,统一地构造二元、三元、多相、复数的ZCZ(LCZ)序列集,且构造简单、形式统一,通用性更好,适用于准同步CDMA(QS-CDMA)系统。

| Abstract: | In this paper,we propose a class of unified constructing methods for zero (low) correlation zone sequences on the basis of the ideal autocorrelation sequence and orthogonal matrix,and the correlation properties are presented and proved.By choosing different se- quences and matrixes,we can construct binary,ternary,complex and polyphase ZCZ(LCZ) sequence sets in these unified methods.The methods possess both simplicity and universality.They are suitable for the QS-CDMA system as spreading sequences. |
