摘要:
 针对矿井巷道中信号传播特性及多径衰落对矿井无线移动通信可靠性的影响，将多输入多输出-正交频分复用( MIMO-OFDM)技术应用于矿井无线通信，给出矿井巷道宽带信道统计模型并建立矿井MIMO-OFDM系统，分析MIMO-OFDM技术在多径衰落下的传输性能。仿真结果表明，系统的误码率随着多径数目的递增而递减，采用MIMO-OFDM技术有效地克服了矿井巷道空间的多径衰落，能极大地提高矿井无线通信系统的性能。
Abstract:
 In view of the impact of signal transmission feature in mine tunnel channel and the multi-path fading on wireless communica-tion reliability in mine tunnel,make the MIMO-OFDM technology used in the mine wireless communication,put forward the statistical model of mine tunnel bandwidth channel and establish the MIMO-OFDM system,analyzing the transmission performance of MIMO-OFDM in multi-path fading. The simulation results indicate that the error rate of system decreases as the number of multi-path increases, MIMO-OFDM technology can resist the multi-path fading of mine tunnel channel,and the performance of mine wireless communication is greatly improved.
