强湍流下并行中继自由空间光通信的中断分析
Outage analysis for parallel relay free-space optical communication in strong turbulence
摘要
Abstract
This paper studies the outage probability for parallel relay Free-space Optical(FSO) communication systems under a condition of strong turbulence. By considering the influences of atmospheric attenuation, atmospheric turbulence and pointing errors on the transmission performance of FSO communication systems, this paper establishes a composite channel model. Based on the model, an analytical expression is further derived for the end-to-end outage probability of parallel relay FSO communication systems. Finally, the effects of transmitted powers, pointing errors and communication distances on outage probability are analyzed through computer simulation. Simulation results show that parallel relay transmission is a promising technology to increase the outage performance and the de-rived analytical expression can provide sufficient precision for evaluating the outage performance of parallel relay free-space optical communication systems, which is helpful to the design of future free space optical communication systems.关键词
