摘　　要：超宽带技术是近年来美国联邦通信委员会批准为民用的高速短距离无线通信技术。对比分析了DS-UWB和TH-UWB2种单载波超宽带系统,在此基础上,为提高频谱利用率,在多径衰落和多用户信道中,给出了一种旨在解决多用户干扰的基于正交Costas序列快跳频的UWB-OFDM系统。UWB(Ultra Wide Bandwidth)is a wireless technology for a high bit rate, short range communication network, recently authorized to be used in public by FCC. With the comparative analyse of the single carrier systems such as DS-UWB and TH-UWB, a novel FFH-UWB-OFDM based on Costas sequence has been proposed in order to make efficient use of spectrum and mitigate MUI(Multi-user interference) in multipath fading channels.

关 键 词：超宽带 DS-UWB TH-UWB Costas正交序列 FFH-UWB-OFDM
