摘要
超宽带技术在无线通信中得到越来越广泛的应用,由于超宽带(UWB)信号占有较宽的频带范围,且被FCC允许在3.1 GHz^10.6 GHz频段范围工作,因此对全球定位系统(GPS)接收机的影响引起了越来越多的关注。文章在介绍超宽带信号特征和对GPS接收机的干扰分析后,给出了一种仿真分析模型,并得到了仿真结果,以及不同脉冲重复频率(PRF)的UWB信号对GPS接收机的影响情况。
Ultra-Wideband technology is gaining increasing interest for its potential application to shortrange indoor wireless communication. Ever since the FCC approved the use of UWB devices in commercial and federal bands, people have voiced concerns over the potential impact of the UWB interference to GPS receiver. Based on the simulation diagram, the potential interference of the UWB pulses with different pulse repetition frequency to GPS receiver is analyzed. Also some simulation results of UWB signal to GPS receivers are given.
