摘要

本文提出了一种新的零相关持续时间(ZCD)序列扩展码。通过对ZCD为(0.75 N-1)的三元优选对(TPP)进行芯片移位运算，生成新的三元ZCD序列集。所提出的三进制ZCD序列具有比二进制ZCD序列更优越的家族大小，在近似同步(AS) CDMA中是有效的。

New ternary spreading codes with zero-correlation duration for approximately synchronized CDMA

In this paper, ternary ZCD (zero-correlation duration) sequences are proposed as the new spreading codes. Novel ternary ZCD sequences sets are generated by carrying out a chip-shift operation of the ternary preferred pairs (TPP) with ZCD of (0.75 N-1) chips. Proposed ternary ZCD sequences have superior family size than the binary ZCD sequences and they are effective for approximately synchronized (AS) CDMA.
