| 摘 要： | 无论是实现直扩信号的盲解扩还是扩频码序列恢复,严格的同步都是算法的关键,同步精度对扩频码序列估计的误码性能有着重要影响。为此提出了一种基于相关脉宽峰值搜索的直扩信号盲同步算法,仿真分析表明,该算法能够较好运用于低信噪比条件下直扩信号的同步点估计。

| Abstract: | Not only blind de-spread spectrum of DS signals,but also reconstruction of PN sequence,the strict synchronization whose precision infects the BER of PN sequence greatly,is the key factor.The blind synchronization algorithm of direct sequence spread spectrum signals based on maximum width of autocorrelation peak is proposed.Simulations show that the algorithm is applied on the estimation of the synchronization point preferably in low SNR. |
