Performance Of A Modified Early-Late Gate Synchronizer For Uwb Impulse Radio

UWB (Ultra-Wide Band) is a promising technology for short-range wireless communications, like in WPAN (Wireless Personal Area Networks) applications. In the context of UWB impulse radio, one of the crucial challenges remains the acquisition of synchronization in terms of time, precision and number of operations. In this paper, we propose a modification of the early-late gate synchronizer for increasing the amount of detected energy, when tracking a time-hopped pulse sequence. The effect of multipath channel is also discussed through simulation results.
