摘　　要：相当数量的传统矿区通讯系统采用OMA(orthogonal multiple access)技术搭建形成,在用户各态历经速率等方面已逐渐不能满足生产需求。该研究将NOMA与全双工协作通信技术融合构建出矿用NOMA(nonorthogonal multiple access)全双工协作通信优化模型,并使用Wi-Fi6和5G中的若干种先进通信技术设计出通讯模型中继传输方法。仿真实验结果显示,两种模型总体中断概率与信噪比呈反比关系。且在相同信噪比条件下,模型二的中断概率明显低于模型三,例如当信噪比为25 dB,模型二、三的总体中断概率分别为0.35和0.76。该项研究结果表明,该研究设计的矿用通信模型在通信速率方面较传统方法有明显的优越性。A considerable number of traditional mining area communication systems are built using OMA(orthogonal multiple access) technology,which has gradually failed to meet the production requirements in terms of user ergodic rate. This research combines NOMA and full duplex cooperative communication technology to build a full duplex cooperative communication optimization model of NOMA(nonorthogonal multiple access) for mining,and uses several advanced communication technologies in Wi-Fi6 and 5G to design the relay transmission method of the communication model. The simulation results show that the overall outage probability of the two models is inversely proportional to the signal-to-noise ratio. Under the same signal-to-noise ratio,the outage probability of model 2 is significantly lower than that of model 3. For example,when the signal-to-noise ratio is 25 dB,the overall outage probability of model2 and model 3 is 0.35 and 0.76 respectively. The research results show that the mining communication model designed in this study has obvious advantages over the traditional methods in terms of communication rate.
