Abstract
Optimum coded Impulse-Radio Ultra-Wideband (IR-UWB) waveforms under power spectral constraints are in- vestigated. Transmission over a SISO frequency-selective channel is assumed. An analytical solution for the optimum precoder is proposed, constraining compliance with a uniform mask in the frequency-domain and maximum transmitted power. Comparison against numerical solutions for non-uniform masks is also per- formed and a generalization of the analytical solution is proposed. Finally, practical design solutions and issues are presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
