Abstract :
Synchronization remains one of the biggest challenges in the ultra-wideband (UWB) impulse radio system. In this paper, a frame-level synchronization algorithm is proposed in differential transmitted reference (DTR) UWB systems in the multipath environment. The signal structure is judiciously designed with the aided data and m-sequence code. Enjoying the fine property of m-sequence autocorrelation function, the proposed algorithm can suppress the noise and inter-frame interference. Moreover, it has very low complexity. Simulation results demonstrate the good performance of the proposed acquisition scheme.
