Pulse-Shaping Numerical Procedures for Ultrawide Bandwidth Systems

This paper deals with the radiation produced by ultrawide-band (UWB) impulse radio transmitters. A numerical procedure is first proposed in order to define the ideal UWB pulse able to be compliant with the FCC emission mask, taking into account the effect of the UWB radiating antenna. The obtained ideal UWB pulse is then decomposed in a linear combination of Gaussian pulses. A numerical procedure for electromagnetic field calculation is finally applied to verify the compliance of the generated pulse with the FCC emission standards
