Modeling the Effects of Interference Suppression Filters on Ultra-Wideband Pulses

In this paper, we study the effects of interference suppression filters (multiple stopbands) on ultra-wideband (UWB) short pulses. Multiple stopbands of the filter, which is placed in the receiver, affect the UWB pulse amplitude, pulsewidth, and ringing; resulting in reduced signal-to-noise ratio an...

Description
Summary:In this paper, we study the effects of interference suppression filters (multiple stopbands) on ultra-wideband (UWB) short pulses. Multiple stopbands of the filter, which is placed in the receiver, affect the UWB pulse amplitude, pulsewidth, and ringing; resulting in reduced signal-to-noise ratio and degradation in receiver performance. An analytical method is proposed in this paper to model the effect of stopbands on the pulse shape. In this paper, the effects of an interference suppression filter on three different Gaussian pulses are studied. Theoretical and measured pulses are compared and found to be in good agreement. The proposed method enables the UWB radio designer to predict the distortion of the received signals after passing through interference suppression filters.
