| 摘 要： | 在准同步CDMA系统中,使用零相关区(ZCZ)序列能够避免共信道冲突和多址干扰。提出了一种新的ZCZ二元序列偶集的构造方法,通过选择合适的正交矩阵,利用扩展方法构造出的新的ZCZ序列偶集合,可以生成长度大于原序列偶的零相关区,不但序列偶长度增加,而且也具有良好的自相关和互相关性能,同时也能满足多用户系统需求。仿真结果表明,它的性能优良,适于作准同步CDMA系统的扩频序列。

| Abstract: | In the quasi-synchronous CDMA systems,use of zero-correlation zone （ZCZ） sequence pairs set can avoid co-channel interference and the multi-access interference.A new method of constructing binary ZCZ sequence pairs set is proposed.The new ZCZ sequence pairs set is constructed by choosing an appropriate orthogonal matrix and using the extended method.A zero-correlation zone with sequence pairs set longer than that of the original ZCZ is generated.Moreover,the new ZCZ sequence pairs set also provides good autocorrelation and cross-correlation performance,and can meet multi-user system requirements.The simulation results show its excellent performance and it＇s suitable for synchronous CDMA system. |
