Abstract

Abstract

A robust blind symbol-timing synchronization scheme applicable to UWB-OFDM systems is presented. The proposed method is based on ZP(Zero-padded Prefix) power collection in the UWB-OFDM symbols whose ZP average power distribute regularly in the slide windows. The synchronization schemes in both Gaussian channel and UWB channel are investigated. Average power distribution of the received signal in UWB channel is analysed detailedly in order that symbol synchronizes accurately. A multi_slide_windows method is designed in order to improve the performance of synchronization. Finally computer results are also demonstrate the superior performance of the new method in both Gaussian channel and UWB channel.
