摘　　要：针对基于无线Mesh网络的井下视频监控系统采用多跳传输技术导致系统容量降低、信号带宽下降等问题,提出在无线Mesh网络中采用多输入多输出技术来提高系统容量,并对多输入多输出系统的容量进行了分析和仿真验证。Matlab仿真结果表明,多输入多输出技术可以在不增加带宽的情况下有效地提高系统容量,解决了井下视频多跳传输过程中带宽下降的问题,从而提高了井下视频实时传输质量。In view of problem that underground video monitoring system based on wireless Mesh network uses multi-hop transmission technique which leads to system capacity and signal bandwidth reducing, the paper proposed to use multi-input multi-output technology in wireless Mesh network to improve system capacity, and analyzed capacity of multi-input multi-output system and did simulation verification. Matlab simulation results show that the multi-input multi-output technology can effectively improve system capacity without increasing the bandwidth, and solve the problem of bandwidth reducing during multi-hop transmission of underground video, so as to improve real-time transmission quality of underground video.
