| 摘 要： | 建立了矿井MIMO信道的模型,推导出该信道模型的空间相关性函数,分析了发送天线端天线间距和接收端天线间距对空间相关性的影响,在此MIMO信道模型的基础上,讨论了矿井的MIMO信道的空间相关性对系统误码率的影响,仿真结果表明,煤矿井下MIMO信道空间相关性越高,系统的误码率就越大。

| Abstract: | This paper establishes MIMO channel model of coal mine,and deduces the spatial correlation function of the channel model.The impact of the antenna distance between transmission antennas and receiver antennas on spatial correlation is also analyzed.On the basis of MIMO channel model,the impact of the space-time correlation of mine MIMO channel on the system BER is discussed.The simulation results show that the higher space-time correlation of MIMO channel in coal mine is,the bigger the system BER is. |

| Keywords: | mine communication MIMO channel model spatial correlation system BER orthogonal spacetime coding |
