Abstract	Ultra wideband (UWB) is a kind of wireless communication system which can perform high data rate with nano-second pulses of baseband, and has recently received much attention for short-range applications. Thus a high sensitivity of timing synchronization between modulation and demodulation is required. Timing synchronization error named timing jitter between transmitter and receiver has been introduced and their properties have been analyzed in some papers. However, there are not many methods brought forward to improve the system performance in the scenarios that deteriorated jitter existents. We consider this problem and offer a method to resist the adverse effect by timing jitter to the whole system by adopting a new designed correlator reference signal in UWB receiver. This reference signal is formed corresponding to the timing jitter distribution of the received pulses waveforms to increase the jitter robust performance. From the simulation results of different UWB modulation systems, better performance can be achieved by adopting this reference signal in the receiver than the conventional schemes.
