Abstract

The performance of time-hopping Ultra-Wideband (UWB) system over IEEE 802.15.3a multipath channel model is analyzed. First, it is proved that the interference between a pulse and its own multipaths cannot be ignored; then a mathematical model is established to evaluate such interference. An exact expression of the average Signal to Interference plus Noise Ratio (SINR) is deduced, which shows that the SINR is determined by the self-correlation function between the channels' parameters and the pulse shape. It is shown that the exact expression is in good agreement with the simulation result. System performances using Gaussian pulse and optimal waveform designed with SDP algorithm are analyzed and compared. Results show that the optimal waveform is more sensitive to multipath interference, which results in worse performance with the same channel parameters.
