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.

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. In particular, the Cramer - Rao Bound (CRB) is presented for the general case of Multiple-Input-Multiple-Output (MIMO) UWB-IR systems and used to compare the ultimate performance of three basic transmit schemes, thereinafter referred to as Single-Input-Single-Output (SIMO), MIMO Equal Signaling (MIMO-ES) and MIMO Orthogonal Signaling (MIMO-OS) ones. Thus, the noncoherent ML synchronizer is developed for the most performing transmit scheme (e.g., the SIMO one) and its performance is 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. © Copyright 2015 IEEE All rights reserved.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
