在不同的无线解决方案中，超宽带（UWB）由于其高数据速率而成为一种很有前途的车载通信技术。为了优化超宽带无线电系统设计，需要了解汽车内的传播信道。本文研究了一种高速480mbps超宽带无线电系统在移动环境下的性能。提出了一套全面的测量方法，包括车辆静止和移动、开窗和闭窗环境以及有/没有乘员时几种可能的非视线场景。这些测量用于表征车内信道，并评估在这种情况下典型UWB无线电系统的性能。
Among the different wireless solutions, ultra-wide band (UWB) is a promising technology for in-car communications because of its high data rates. To optimise the UWB radio system design, knowledge of the propagation channel within the car is required. The performance of a high-speed 480 Mbps UWB radio system is studied within a real in-car environment measured under mobility. A comprehensive set of measurements is presented, including several possible non-line of sight scenarios while the vehicle is stationary and mobile, for open-and closed-window environments and with/without occupants. These measurements are used to characterise the in-car channel and evaluate the performance of a typical UWB radio system in this setting.
