车辆内的电子娱乐设备的增加已经提出了用车内个人局域网代替有线链路的想法。超宽带（UWB）似乎是一种合适的候选技术，可以满足互连此类设备所需的数据速率。尤其是，多频带OFDM（MB-OFDM）能够在相对短的距离和低发射功率下提供很高的传输速率（最高480 MBps）。为了评估车辆内UWB系统的能，需要可靠的信道模型。在本文中，研究了一种游牧系统，在该游牧系统中，位于仪表板中央的基站希望与位于后座的固定设备进行通信。提出了用于车内通信（IVC）系统的单输入单输出（SISO）通道模型，基于混响室理论 该模型基于在实际交通条件下进行的测量，并且汽车中的乘客数量有所不同。无线信道的时间变化也被表征和参数化。通过比较独立于模型的统计数据与度量值来验证所提出的模型。

　　The increase in electronic entertainment equipments within vehicles has rendered the idea of replacing the wired links with intra-vehicle personal area networks. Ultra-wideband (UWB) seems an appropriate candidate technology to meet the required data rates for interconnecting such devices. In particular, the multiband OFDM (MB-OFDM) is able to provide very high transfer rates (up to 480 MBps) over relatively short distances and low tranit power. In order to evaluate the performances of UWB systems within vehicles, a reliable channel model is needed. In this paper, a nomadic system where a base station placed in the center of the dashboard wants to communicate with fixed devices placed at the rear seat is investigated. A single-input single-output (SISO) channel model for intra-vehicular communication (IVC) systems is proposed, based on reverberation chamber theory. The model is based on measurements conducted in real traffic conditions, with a varying number of passengers in the car华体会最新地址. Temporal variations of the wireless channels are also characterized and parametrized. The proposed model is validated by comparing model-independent statistics with the measurements.hth网页版在线登录
