Narrowband Interference Elimination in UWB Communications Systems

Abstract

This paper proposes a narrowband interference cancellation for UWB communication systems. The cancellation unit estimates and generates the interferer then eliminates it by subtracting to a delay version of the UWB signal. This mitigation technique provides a gain between 3 dB to 5 dB in multipath environment with the presence of a single ODFM WLAN interferer.
