| 摘 要： | 由于矿井隧道的特点,采用微波频段的井下移动通信系统在工作时会出现明显多径效应和多普勒频移效应。井下无线信号的传输属于有限空间的信号传输,多径效应的影响是比较严重。本文主要讨论的是井下大巷与斜巷对无线视频信号的不同影响。

| Abstract: | The mobile telecommunication system working at the microwave band will come to the multi-path effect and arouse Doppler phenomenon in the coal mine tunnel.Underground wireless signal transmission belongs to the transmission of limited space,and its multi-path effects are more serious.This paper mainly discusses the different effects that underground inclined roadway and alleys have on the wireless video signals. |
