摘　　要：矿井巷道电波传播环境非常复杂,建立MIMO无线信道模型有助于将无线通信技术应用到煤矿井下。针对矿井巷道中MIMO无线传输环境,提出一种随机独立的MIMO信道,然后根据矿井巷道的富散射环境,对该信道矩阵进行修正,建立了两种空间相关的MIMO信道模型。文章对包含完全独立路径的瑞利信道模型的奇异值和信道容量进行了分析比较,并对不同信道模型下的系统性能进行了仿真。仿真结果与文献的实测结果对比说明建立的模型不失一般性。The radio propagation situation is very complex in mine laneway,so it is important to establish an efficient MIMO channel model for applying wireless communication technology to coal underground.A stochastic MIMO channel model was proposed firstly based on wireless propagation environment in mine tunnel,and then two spatial correlative channel models were established through correcting channel matrices based on abundant scatter environment.The singular values and the channel capacity obtained with a Rayleigh channel model were compared,and system performance of different channel models were simulated.The simulation results indicate that the established channel models are feasible by comparing with measurements results.
