چکیده مقاله:
A new Ultra Wideband (UWB) pulse shape is proposed to mitigate coexistence issues of IEEE802.11.a WLAN and Impulse Radio UWB (IR-UWB) systems. The proposedmethod is applicable to the reduction of any given narrowband (NB) interference into UWB systems. This pulse shape is basedon frequency up-converting of first derivative of Gaussian pulse which has an adjustable null in Power Spectral Density (PSD)depending on up-converting frequency. Both analytical andsimulation results with an adaptive receiver show that an UWB system with interference from a WLAN has noticeable improved performance when using the proposed pulse in comparison with using conventional modulated Gaussian pulse
