摘　　要：针对煤矿井下无线通信环境的复杂性和特殊性,将MIMO技术与CD-FM-DCSK混沌键控通信系统相结合进行可行性研究。以2发送2接收天线空时编码为例,对其在煤矿井下的通信性能和传输特性进行仿真分析。仿真结果表明,MIMO-CD-FM-DCSK可以较好地克服多径衰落,获得更优异的通信性能。同时,对于不同的E_b/N_0取值,选择合理的扩频因子能够实现该通信方案性能的最优。In view of the complexity and particularity of the coal-mine wireless communication environment,MIMO technology is combined with CD-FM-DCSK Chaos keying communication system for feasibility study.With the space-time coding of 2 transmitting and 2 receiving antennas as an example,its communication performance and transmission characteristics in coal mine are simulated and analyzed.Simulation results indicate that MIMO-CD-FM-DCSK could overcome multipath fading and achieve better communication performance.At the same time,for different Eb/N0 values,the proper selection of spreading factor can achieve the best performance of the communication scheme.
