Abstract :
We analyse the power spectral density of time hopping (TH) coded impulse trains in ultra-wideband (UWB) systems, where the codes are described by their period and probability distribution. Thereby a number of significant code parameters are derived, which provide appropriate spectral smoothing properties. Furthermore the power spectrum of UWB impulse trains applying three different coders for time hopping are compared.
