A Vehicular Ultra-Wideband Channel Model for Future Wireless Intra-Vehicle Communications (IVC) Systems

Future wireless intra-vehicle communications (IVC) systems adopting ultra-wideband (UWB) radio are proposed in this paper, which provide onboard passengers with high-speed duplex data exchange services. In this paper, a vehicular UWB channel model is first developed by modifying the IEEE 802.15.3a indoor model to fit into the vehicular environments with dense and concentrated clusters and rays. The main channel statistical parameters, such as maximum excess delay, root mean square delay and the number of multipath components are then theoretically deduced. Next, the proposed vehicular model is verified by experimental data gained from a measurement campaign conducted within a pickup truck, which lays down a solid foundation for theoretical analysis and system design for future wireless IVC systems.
