| 摘 要： | 针对矿井巷道的特殊环境以及无线通信问题，通过MIMO系统和分布式天线系统，建立了井下分布式MIMO信道模型。仿真结果表明，分布式MIMO系统具有更高的信道容量。基于分布式天线的灵活设置，分布式MIMO系统既提高了频谱利用率又减少了信号盲区，最终扩大了井下信号覆盖范围，提高了整个系统的信道容量。

| Abstract: | According to special space environment of the mine tunnels and problems of wireless communication system, this paper analyzed MIMO technology and distributed MIMO technology, and designed the distributed MIMO channel model of underground coal mine. The simulation results show that distributed MIMO system has a better capacity than that of MIMO system. With the flexible set of distributed antennas, distributed MIMO system not only improved spectrum utilization but also reduced the signal blind area, eventually distributed MIMO system expanded the underground signal coverage and improved the channel capacity of the entire system. |
