摘要

介绍了陆地移动通信系统和卫星移动通信系统中传播信道的宽带测量。在对测量系统进行简要描述后，讨论了测量计划的细节。对测量数据的分析主要集中在从功率延迟谱(即所谓的延迟剖面函数)计算的RMS延迟扩展值上。研究了接收噪声水平对RMS延迟扩展计算的影响，并给出了特征图。

Noise threshold dependency of the RMS delay spread in wideband measurements of radio propagation channels

Wideband measurements of the propagation channel in land mobile and satellite mobile communication systems are presented. After a short description of the measurement system the details of the measurement plans are discussed. The analysis of the measured data is mainly focused on the RMS delay spread values calculated from the power delay spectrums (or so-called delay profile functions). The effect of the received noise level on the calculation of the RMS delay spread is investigated and characteristic diagrams are presented.
