Performance Analysis of Dual Ground Station Laser-Microwave Hybrid Links Based on Markov Model
针对气象变化对自由空间光(Free Space Optical,FSO)通信链路和毫米波射频(Radio Frequency,RF)通信链路可用率的影响问题,采用马尔科夫建模与稳态概率求解计算方法,分析不同天气条件下FSO/RF混合链路的双接收站分集与中断概率性能.基于FSO链路和RF链路的信道模型,采用有限状态马尔科夫链(Finite State Markov Chain,FSMC)分别对单双站FSO/RF混合链路的切换选择进行建模,推导得出不同参数和天气情况下系统稳态的中断概率表达式.数值计算结果表明,当中断概率达到10

Abstract
Aiming at the system availability problem of free space optical (FSO) link and millimeter wave radio frequency (RF) link under various meteorological conditions
multiple ground station diversity and system outage probability performance were investigated by using Markov model steady-state probability equilibrium method. Based on the channel models of FSO link and RF link
hybrid link selection finite state Markov chain (FSMC) was established for single and dual station scheme respectively. Then their outage probability expressions were derived and calculated under different system parameters and weather conditions. Numerical results show that at outage probability 10

with link distance 1~7 km under rainy and foggy weather conditions
the dual ground station FSO/RF hybrid link can achieve 4~25 dB gain compared to single station case.
