| 摘 要： | 在对直接扩频通信系统的信号及技术实现特点进行分析的基础之上,提出了采用多相关器实现BPSK直扩信号解扩的方法。采用多相关器进行BPSK直扩信号的解扩,改善了高动态变化条件下接收机的同步及跟踪性能;通过控制本地解扩序列的产生方式,提高了接收机对不同使用条件的适应能力,较之采用单相关器的解扩方法,其适应能力更强。通过仿真验证证明了该方法的有效性。

| Abstract: | The method that uses multicorrelator to implement the dispreading of direct sequence spread-spectrum （DSSSS） is dis-cussed in this paper based on analyzing the characteristics of DSSS signal.This method can improve the the synchronization and trackingperformance of the receiver in high dynamic changes environment;It can improve the adaptability of receiver for different conditions bychanging the local generation of spreading codes.Compared with the dispreading method of signal correlator,it has a higher adaptability.The simulation results show that this method is available. |
