摘　　要：为了解决PMA-DCSK通信系统中置换与逆置换的同步问题,提出了一种基于滑动相关法的PMA-DCSK同步方案,借鉴直接序列扩频系统中PN码的同步思想,通过对假同步概率、漏同步概率和同步平均建立时间的理论分析,对同步方案进行了性能评估。理论分析和仿真结果验证了同步方案的有效性,为PMA-DCSK系统实用化和信号参数选择提供了理论依据和数据参考。To solve the synchronization problem of transformation and inverse transformation in PMA-DCSK chaotic communication system, a synchronization scheme based on sliding-correlation method is proposed. According to the synchronization theory of DSSS system, theoretical analysis of false synchronization, leak synchronization and mean synchronization-building time is given. Results of theoretical analysis and simulation show the effectiveness of the synchronization scheme and theoretical basis and data reference are provided for practical design and parameter selection of PMA-DCSK system.
