准同步(QS-CDMA)多址系统扩频序列(PN)设计

在本文中，对普遍的准同步ＱＳ直序ＤＳ码分多址ＣＤＭＡ通信系统和最佳扩频伪随机序列ＰＮ的设计作了论述。通过用矩阵法设计在一定的偏移范围内具有优良的伪随机性和很小的互相关值。与其它序列不同的是，本文中的ＰＮ序列产生小的多址干扰（ＭＡＩ）。

PN Sequence Design for Quasisynchronous CDMA Communication Systems

In this paper,the quasisynchronous(QS)direct sequence(DS)code-division multiple access(CDMA)communication system is generalized,and the problem of optimal spreading pseudonise(PN)sequence design is formulated The classes of optimal PN sequence which have good pseudo-randomness and very small cross-correlation values for some range of offsets are designed with a matrix-based approach Unlike other sequences,PN sequence produces small multiple-access interference(MAI)
