提出了一种DS/SS信号盲同步算法，在此基础上利用特征分析法可解决相位不确定性的缺陷。该算法简单有效、计算量小，利于硬件实时处理。理论分析及计算机仿真结果表明，该算法在低信噪比条件下可实现DS/SS信号的盲同步及PN码序列的精确估计。
In the lower Signal to Noise (S/N) ratio Direct Sequence Spread Spectrum (DS/SS) signals, the estimated Pseudo-Noise (PN) sequence has a problem of phase indetermination in the method based on eignanalysis techniques. In this paper, we propose a simple and valid approach to blind synchronization of DS/SS signals. The problem above can be resolved by the blind synchronization algorithm. The theoretic analysis and experimental results show that the approach can work well on the lower S/N ratio input signals.
