An Effective Synchronization Scheme for DHTR UWB Receiver

In this paper, we propose an effective synchronization scheme which is suitable for UWB impulse radio systems under noise and ISI channels. Traditionally, the synchronization scheme for UWB system only support single user environment. However, our proposed algorithm could support multiuser environments. Based on the architecture of our proposed UWB receiver, the uncertain region is limited to one frame duration. Besides, owing to the parallel search mechanism, it can appreciably reduce the total search time for the synchronization algorithm. However, our proposed UWB receiver needs higher circuit complexity.
