zcw

However , the code resource is very limited for ZCW spreading codes and the complexity of joint detection is huge when the number of code channels takes large .

但二者都有一定局限性，对于零相关窗码来说，它的码字资源十分有限，对于联合检测来说，当用户数很大，它的复杂度不能容忍。

The 0 ~ 5 months PA of the ZCW coupled model is worse than that of the persistence forecast , and vice versa for after 5 months .

提前0~5个月的耦合模式预报能力小于同期持续预报能力，之后则相反；

A novel type of spreading access codes with set-wise zero correlation window ( ZCW ) is proposed for minimum orthogonal frequency shift multicarrier direct spread code division multiple access ( CDMA ) system in which the carrier gap is half of the reciprocal of the chip cycle .

为了设计出载波间隔只有码片周期倒数一半的多载波直接扩频系统，提出了一类分组零相关窗（ZCW）地址码。
