报告摘要：
By utilizing massive connected devices and automatic mining vehicles, the intelligent mining systems can ensure the safety of life and property of mining industry. Aiming at the demands of massive connected devices, even faster transmission rate, various quality of service (QoS), we classify the applications into two typical scenarios, i.e., the crowded scenario (Rayleigh channel) and the rare device scenario (Rician channel). To tackle down the ergodic capacity expression’s intractable calculations in both scenarios, we further obtained their simplified approximate expressions. Numerical results demonstrate the validity and effectiveness ofour analytical results. Compared to MC method, the consumed time is greatly reduced by our derived expressions. Simulation results also demonstrated that the system capacity performance can be enhanced by increasing the transmit NOMA power and Rician factor (Rician scenario), and the effectiveness of FD-NOMA is determined by the FD self-interference and the channel noise. In addition, FD-NOMA can greatly reduce the system latency compared to other schemes.
智慧矿山系统通过布点大量的传感器以及自动化无人作业车系统可以极大地节省人力，保障矿产和从业人员的生命安全。针对智慧矿山设备应用的大连接高速率低时延多样性QoS需求，本研究提出划分应用场景为典型视距以及视距非视距混杂两种典型场景，并通过数学推导给出了系统遍历容量的近似闭式表达式，仿真实验表明与现有研究相比，本论文的闭式表达式具有较高的精度和较低的计算复杂度，此外，仿真实验证明了全双工非正交多址接入可以降低系统的时延；系统遍历容量随传输功率以及莱斯因子增加而增加；双工自我干扰以及信道噪声是影响系统遍历容量的决定性因素。
