Abstract
The applications of ultra wideband (UWB) systems in commercial vehicles are increasingly attracting attention recently. This paper aims to lay a solid foundation for the use of UWB radio in vehicular environments by measuring both intra-vehicle and inter-vehicle UWB channels. At first, a comprehensive measurement campaign was conducted to gather a set of channel impulse responses of UWB channels under several typical scenarios. The UWB vehicular channel is analyzed and compared with the IEEE 802.15.3a indoor model. Next, the bit error rate (BER) against signal to noise ratio (SNR) curves of UWB systems applied in commercial vehicles are presented, analyzed and compared to the performance of indoor UWB systems based on the IEEE 802.15.3a model.
