A NEW SYNCHRONIZATION SCHEME USING PERFECT PUNCTURED BINARY SEQUENCE PAIRS IN DS-UWB SYSTEM

摘要

Ultra WideBand (UWB) radio is a new wireless technology that transmits extremely short durationradio impulses. In this paper, a new synchronization scheme is proposed in Direct Sequence (DS) UWB sys-tem using Perfect Punctured Binary Sequence Pairs (PPBSP) as the preamble. It can acquire both Pseudo-Noise (PN) sequence and frame synchronization at the same time. The properties and the combinatorial admis-sibility conditions of PPBSP are presented. The simulation results show that PPBSP is good for synchroniza-tion by their good cross-correlation properties both under Additive White Gaussian Noise (AWGN) channeland modified Saleh-Valenzuela channel.
