Timing synchronization in impulse-radio UWB: Trends and challenges

This paper studies the analog implementation of timing synchronization in impulse radio UWB systems. An insight into various UWB modulation schemes is provided, and an overview of the state-of-the art synchronization techniques is discussed. A novel method is presented for high-speed timing synchronization of UWB receivers in analog domain. The required timing resolution is determined and system-level simulations validating the technique, are demonstrated.
