A New Synchronization Scheme Exploiting Mean Energy Profile in UWB Non-coherent Receiver

We introduce a new synchronization scheme to improve the synchronization performance in a ultra-wideband (UWB) non-coherent energy collection receiver. Our proposed scheme exploits the mean normalized energy profile, which is known at the receiver, to acquire synchronization. The synchronization process is performed through comparing the energy collected from the received signal with the mean normalized energy profile and correcting the timing error. The synchronization performance is investigated in terms of the normalized mean squared synchronization error (NMSSE) in IEEE 802.15.3a UWB indoor channel environment. Through simulation results, we show that the proposed scheme enhances the synchronization performance.
