- In this paper, we implement a novel UWB channel model simulator modifying by the conventional UWB channel model(IEEE 802.12 SG3a) parameters and also try to improve the UWB system performance applying by the modified channel parameters. First of all, we find the newly modified channel parameters adopting by the characteristic which the circularly polarized wave has markedly fading reduction effect compared to the linearly polarized wave in the indoor LOS and NLOS environment. And also, we modify main channel parameters(cluster arrival rate, ray arrival rate, cluster decay factor, ray decay factor) based on measured data for establishing the correct channel model corresponding to various polarized waves. Finally, in oder to verify the modified channel parameters, we analyse the performance improvement of UWB system.
