Abstract:

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.

Key words: ultra-wideband, pulse, narrowband interference, interference suppression
