摘要

研究了低相关带和零相关带序列在准同步DS/CDMA通信系统中的应用。描述了几种具有LCZ和ZCZ的序列。数值结果表明，在用户数量相同、处理增益基本相同的情况下，采用ZCZ序列和LCZ序列的系统的误码率性能相当。此外，当时序误差较大时，ZCZ序列的性能优于LCZ序列。通过仿真验证了分析结果。

Spreading sequence sets with zero and low correlation zone for quasi-synchronous CDMA communication systems

This paper considers the application of sequences with low correlation zone (LCZ) and zero correlation zone (ZCZ) to quasi-synchronous DS/CDMA communication systems. Several classes of sequences with LCZ and ZCZ are described. Numerical results show that the BER performances of systems using ZCZ sequences and LCZ sequences are comparable with the same number of users and almost the same processing gain. In addition, when the timing error is large, the ZCZ sequences perform better than the LCZ sequences. Analytic results are verified with simulations.
