Abstract :
This contribution focuses on the (up to date unexplored) topic of the maximum-likelihood (ML) noncoherent synchronization of multi-antenna transceivers working in faded environments and employing ultra wide band impulse radio (UWB-IR) transmit technology. The noncoherent ML synchronizer is developed for the most performing transmit scheme (e.g., the SIMO one) and its performance are evaluated under both signal-acquisition and tracking operating conditions. The performance gain in the synchronization of UWB-IR signals arising by the utilization of the multi-antenna technology is also evaluated.
