摘要 多输入多输出(MIMO)技术可有效地抵抗矿井巷道中无线传输多径衰落现象,文章分析了矿井MI-MO信道容量所受影响因素,研究了MIMO系统的具体散射环境和天线阵列的相关性,建立了矿井MIMO相关信道模型,并对不同的相关系数进行了数值分析;结果表明,MIMO系统性能受矿井巷道的空间相关性影响非常大。 The multipath fading problem in mine roadway can be resisted by using multiple-input multiple-output（MIMO） technology. The influential factors to mine MIMO channel capacity are analyzed, and the idiographic scattering circumstance and the correlation of antenna array are researched. Then the MIMO channel model of correlative antenna is established, and different correlative coefficients are simulated. The simulation results indicate that the performance of mine MIMO system is primarily depended on spatial correlation of mine roadway.
