基于马尔科夫模型的双站激光微波混合链路性能分析
Performance Analysis of Dual Ground Station Laser-Microwave Hybrid Links Based on Markov Model
摘要
Abstract
Aiming at the system availability problem of free space optical(FSO)link and millimeter wave radio fre-quency(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 du-al station scheme respectively.Then their outage probability expressions were derived and calculated under different sys-tem parameters and weather conditions.Numerical results show that at outage probability 10-6,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.关键词
