摘　　要：提出了一种基于数据辅助的IR-UWB脉冲同步方法.该方法利用正交正弦相关,将脉冲相对相关窗的位置映射为接收向量的相位,从而利用正交相关的取样值估计同步误差.给出了同步的原理以及相应的数学模型,并推导了同步环路的传递函数.仿真结果表明该方法能够实现快速脉冲同步.A novel data-aided pulse synchronization method applied in IR-UWB communication system was presented. The proposed method maps the pulse position relative to the correlation window to the phase of received vector through orthogonal sinusoidal correlation, and hence estimates the synchronizing error with the sampling value of the orthogonal correlation. The principle of the new method was studied as well as the corresponding mathematical model, and the transfer function of the synchronizing loop was provided. Implementation results show that the system can achieve synchronizing fast when applying the new method.
