| 摘 要： | UHF测段陆地卫星移动业务多径实验于1999年6月至8月间利用日本GMS140E气象卫星为信标，分别在河南郑州至开封高速公路、林州至上党方向公路以及石家庄至阳泉高速公路段进行。地面接收系统和数据处理设备安置于汽车上。此项实验的目的是为地面卫星移动通信系统的设计提供重要的信道参数。本文给出了不同环境下多径效应的累计分布特性以及相应的预测模型。

| Abstract: | Multipath environment measurements at UHF were performed in speedway Zhengzhou to Kaifeng and highway Linzhou to Shangdang and speedway Shijiazhuang to Yangquan in June and August 1999 The experiment employed the satellite GMS140E as a source platform Also the experiment used a van with receiver and data acquisition instrumentation The experiment were performed for the purpose of providing the important link parameter with the design of land mobile satellite systems;namely the expected fading statistics due to multipath The cumulative fade distributions and empirical regression models are derived from the various Multipath environment field measurements |

| Keywords: | land mobile satellite system multipath cumulative distribution modeling |
