摘要
In this paper, a coarse synchronization scheme is proposed through introducing a digital matched filter combining diversity according to the same time hopping (TH) as the expected user in ultra wideband (UWB) communications. By analyzing the signal characteristic, the filter window parameters are set to utilize sufficient energy from the receiving signal in a multipath environment. The receiver can spend about one bit duration in achieving acquisition, which indicates the receiver presented here can efficiently improve the acquisition performance.
