摘　　要：提出了一种能够抑制多个窄带干扰的超宽带(UWB)脉冲设计方法.采用这种方法设计的UWB脉冲不仅具有非常短的脉冲持续时间,而且能够在满足联邦通信委员会(FCC)频谱限制的基础上,进一步抑制UWB系统与多个窄带通信系统之间的相互干扰,从而有效地解决了UWB系统与现有的窄带通信系统之间的共存问题.另外,此方法不需要在整个频段范围内降低UWB脉冲的功率谱密度,为提高UWB脉冲发射功率,增大UWB系统的通信距离,提供了一种可行的方案.An ultra-wideband (UWB) pulse design approach for multiple narrowband interference suppression was presented. The generated UWB pulse not only has a very short time duration, but can entirely meet federal communications commission (FCC) spectral mask and effectively suppress the interferences between UWB systems and multiple narrowband communication systems. The coexistence problem between UWB systems and the existing narrowband systems was successfully solved after that. In this approach, the power spectral density of UWB pulse does not need to be reduced over the whole frequency band. Therefore, it is possible to enlarge the communication range of UWB systems by increasing the transmitted power of UWB pulses.
