Non-Linear Chirp UWB Ranging System With Narrowband Interference Suppression Abilities

In this paper, the authors analyze an ultra-wideband ranging system based on non-linear chirp waveforms with the ability of narrowband interference suppression. A number of non-linear chirp waveforms are proposed and evaluated by simulation. The results verify that the proposed schemes can suppress the Narrowband interference to a certain degree. Ultra-WideBand (UWB) systems occupy ultra wide bandwidth that has been assigned to other existent NarrowBand (NB) wireless applications; thus, NB applications degrade UWB ranging system performance or even cause it to malfunction. The method of using non-linear chirp waveforms to suppress NBI has been proposed.
