Rapid Synchronization for Noncoherent UWB Systems

In this paper, a novel rapid synchronization algorithm is proposed for UWB systems with noncoherent receivers based on an energy capture scheme, fully exploiting adequate multipath component. Only one symbol observation is required to acquire synchronization, which speeds up the overall synchronization process. And the lower complexity is achieved via not only the synchronization scheme but also the noncoherent receiver. Simulations are performed to demonstrate the promising performance of the presented algorithm.
