Interference detection and rejection in ultra-wideband systems

Ultra-wideband (UWB) communication systems appear promising for many wireless applications. However due to the restraint on their transmission power levels, UWB systems unavoidably suffer from the interference caused by the coexisting systems, making it extremely difficult/impossible to maintain adequate signal-to-noise-and-interference ratio (SNIR) levels. This paper presents a solution to this problem through use of agile filters to detect and eliminate narrowband interference.
