Abstract :
Ultra-wideband (UWB) communications employ very short pulses with different modulation that result in extremely wideband spectra for high data-rate links. These spectra are a function of both the spreading operation as well as the pulse shapes. We propose a pulse spectrum optimization technique based on classical filters. Non-ideal impulse characteristics are then considered and the optimum pulse derived for either minimal energy (highest spectral bandwidth). The motivation is to show that filtered pulses can achieve significant spectral control in direct baseband UWB signals for high data-rate communications.
