The Synchronization Technique in IR-UWB Wireless Communication System

The synchronization technique in IR-UWB(Impulse Radio Ultra Wideband)wireless communication system is discussed in this paper,and the research situation at present is presented.The pulse shape and channel model are discussed,then from the point of view of signal processing,the two different synchronization techniques: detection-based approach and estimation-based approach are compared.And a survey on main current synchronization techniques based on the two different theories is presented,focusing on the approach,characteristic and performance of several synchronization methods.The main problem in the IR-UWB synchronization technique and the potential research direction in the future are pointed.
