| 摘 要： | 针对MC DS-CDMA系统对定时误差敏感的特点,提出一种全数字定时跟踪方案.通过对准时支路相关值进行矢量旋转,检测定时误差并实现定时调整跟踪.理论分析和数值结果表明,与传统方案相比,在不牺牲性能的前提下,新方案成倍降低了实现复杂度.硬件电路实现验证了方案的可行性.

| Abstract: | A novel reduced-complexity timing tracking algorithm suited for multi-carrier DS-CDMA signals based on vector rotation is proposed and studied. Theoretical and numerical results shows that the new scheme has a remarkable decrease of complexity but no performance degradation when compared to the conventional. |
