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.
