Spectral Efficient Pulse Shaping for Impulse Radio Ultra Wideband Communications

Abstract

Efficient pulse shaping techniques are required in UWB communication systems to fit the Federal Communication Commission (FCC) mask with reduced interference with other narrow band systems. We propose a pulse shaping technique to fit the FCC mask efficiently by employing our proposed band pass filter. The UWB pulse shape is spectrally modified and analyzed to prove its ability in achieving higher spectral utilization efficiency without employing any optimization techniques as in literature. The proposed band pass filter for pulse shaping has features of sharp transition, desired stop band attenuation and expression for filter coefficients which enables flexible spectral shaping to fit any FCC mask efficiently.
