论文摘要
在本文中，我们研究了强大时变距离的影响对低地球轨道（LEO）卫星 - 事物传输（STT）系统的性能的影响。我们建议使用有限状态马尔可夫通道（FSMC）模型和时间离散方法提出一个新的分析框架。此外，为了证明所提出的框架的应用，评估了两种自适应传输，自适应传播（大鼠）和功率自适应传输（PAT）方案的性能，以固定在LEO卫星处的发射功率或传输速率的情况下。得出和验证了考虑的系统的闭合表达式，能效（EE）和延迟中断率（DOR），可以通过拟议的分析框架来解决所考虑的LEO STT方案的容量，能效和中断率的性能。
In this paper, we investigate the effect of the strong time-varying transmission distance on the performance of the low-earth orbit (LEO) satellite-terrestrial transmission (STT) system. We propose a new analytical framework using finite-state Markov channel (FSMC) model and time discretization method. Moreover, to demonstrate the applications of the proposed framework, the performances of two adaptive transmissions, rate-adaptive transmission (RAT) and power-adaptive transmission (PAT) schemes, are evaluated for the cases when the transmit power or the transmission rate at the LEO satellite is fixed. Closed-form expressions for the throughput, energy efficiency (EE), and delay outage rate (DOR) of the considered systems are derived and verified, which are capable of addressing the capacity, energy efficiency, and outage rate performance of the considered LEO STT scenarios with the proposed analytical framework.
