主 题:loosely synchronous spreading sequence Kronecker product ZCW
摘 要:A new class of loosely synchronous(LS)spreading sequences with zero correlation window(ZCW)was *** was constructed by making Kronecker product of orthogonal matrix and ZCW complementary *** new LS sequence increases the number of perfect complementary pairs and extends ZCW within the same ***,both auto-correlation and cross-correlation of ZCW in the same group remain *** minimum ZCW among different groups is the same as that of basic LS *** method for constructing these new LS sequences is presented and ZCW properties are also *** number of these new LS sequences is only smaller than theoretical upper bound by one.
