论文摘要
本文研究了多门下行链路远程（LORA）网络的系统级性能。 具体而言，我们首先计算通道的活动概率以及闭合形式表达式中有源端机（ED）的选择概率。然后，我们在捕获效果和不同扩散因子（SF）分配方案的影响下得出覆盖率（PCOV）和面积光谱效率（ASE）。 我们的发现表明，通过增加占空比和发射功率，可以显着增强PCOV和所考虑网络的ASE。 最后，提供了蒙特卡洛模拟，以验证提出的数学框架的准确性。
The system-level performance of multi-gateway downlink long-range (LoRa) networks is investigated in the present paper. Specifically, we first compute the active probability of a channel and the selection probability of an active end-device (ED) in the closed-form expressions. We then derive the coverage probability (Pcov) and the area spectral efficiency (ASE) under the impact of the capture effects and different spreading factor (SF) allocation schemes. Our findings show that both the Pcov and the ASE of the considered networks can be enhanced significantly by increasing both the duty cycle and the transmit power. Finally, Monte-Carlo simulations are provided to verify the accuracy of the proposed mathematical frameworks.
