| 摘 要： | 直接扩频通信(DSSS)作为通信领域有效扩展频谱的前沿技术,由于其隐蔽性好,抗干扰性强,速率高等特点,已被广泛应用许多领域。同步系统是扩频通信的关键技术,扩频序列的同步分为扩频序列的搜捕和跟踪两个阶段。本论文研究的重点是在伪码完成粗同步(捕获)之后能保持良好的同步跟踪,从而有效地、可靠地工作。

| Abstract: | Direct Spread Spectrum Communications DSSS is a cutting technology spreading the spectrum of transmitted signal,it has been widely used to many different areas due to its invisible,high anti-interference and high speed and effectiveness and safety.Synchronization spectrum sequence spread-spectrum sequences are divided into two stages of the acquisition and tracking.Finishing coarse synchronization of PN and keep tracking effectively so as to work stably and reliable. |
