Abstract

The impulse response of the impulsator affects the power spectrum density (PSD) of ultra-wideband (UWB) transmitted signal directly. The Gaussian derivative pulse is easy to be produced by impulsator and is used broadly in UWB pulse. We proposed a simple pulse design method that made use of a linear multi-pulse combination of a Gaussian derivative or mono-pulse combination of multiple Gaussian derivatives and proposed to optimize its weight vector by genetic algorithm (GA). The experimental results showed that the designed pulse can meet the power spectral constraint of Federal Communication Commission (FCC) UWB mask and its performance is better than single Gaussian derivation pulse to satisfy some demand .
