Abstract :
This paper studies the performance of ultra wideband (UWB) communication systems in AWGN channels. The studied UWB systems are utilizing different kinds of modulation schemes. The propagating information signal is jammed with a signal having a spectrum in the UMTS or in the GSM band. The simulations showed that the time hopping UWB system utilizing binary PAM modulation outperforms the other studied modulation schemes in the AWGN channel when a jamming signal is present. The simulation results showed that the rank order of the studied modulation schemes in the AWGN channel in the presence of jamming is time-hopping binary pulse amplitude modulation. direct sequence based binary pulse amplitude modulation, time hopping pulse position modulation and direct sequence based on-off-keying.
