| 摘 要： | 介绍了针对车内环境进行的宽带信道特性测量结果和提取的信道特性.测量的信道频率范围为0.5～16 GHz,场景包括了直达径(Line-of-Sight,LOS)和非直达(Non-Line-of-Sight,NLOS)的典型情况,同时也考虑了收发距离和车内乘员的影响.测量结果显示:车内环境下的小尺度多径衰落模型可以使用Saleh-Valenzuela(S-V)模型进行描述.车内的幅度衰落统计特性服从Lognormal分布.从测量的数据中提取了均方根时延扩展和S-V模型的关键参数.进一步的研究显示:均方根时延较少依赖于传输距离,主要取决于车内的环境、人员数量和布局.统计得出的信道参数和分布特性可以建立离散时间信道模型,应用于仿真与验证宽带通信系统.

| Abstract: | This paper presents the result and characteristic extracted from the wideband channel measurement campaigns conducted from in-vehicle environment.In the experiment,the measurement is carried out within the frequency range of 0.5~16 GHz.Typical in-vehicle scenarios,such as line-of-sight(LOS) and non-line-of-sight(NLOS),are included.The influence of different distance and impact of passengers are also considered.Results show that the Saleh-Valenzuela(S-V) model could be used to describe the small-scale fading... |
