| Ultra-wideband wireless is an emerging communication technology which offers promise as a solution for high capacity short-range multiple access systems. Multiple access interference for the time-hopping ultra-wide bandwidth systems has been analyzed by many literatures in recent years, where the conventional matched filter ultra-wide bandwidth receiver is adopted as the receiver detector. However, the conventional matched filter ultrawide-band receiver is not necessarily an optimal receiver since the multiple access interference in the time-hopping ultra-wide bandwidth systems is not Gaussian distributed.; In this thesis, an ultra-wideband receiver is proposed based intuitively on the simulated probability density function of multiple access interference for the time-hopping ultra-wideband systems. The new ultra-wideband receiver dubbed the "zonal" receiver is shown to have better performance than the conventional matched filter ultra wideband receiver in multiple access interference channels with or without the presence of the additive white Gaussian noise. |
