一种融合自由空间光和毫米波通信的链路容量优化模型
A link capacity optimization model incorporating free space optical and millimeter-wave communication
摘要
Abstract
In order to enhance the ability of free space optical(FSO)to withstand bad weather,an optimiza-tion model of three-hop link capacity based on UAV relay(UAV-LC)is proposed in this paper.On the basis of not affecting the source FSO node and the destination FSO node,a millimeter wave(MMW)link is constructed on the second hop link by using the UAV,and FSO links are still used on the first hop and the third hop link.Since the UAV position is related to MMW link length and FSO link length,an objective function for the optimization of the entire link capacity of the UAV position is first constructed.Then Newton-Raphson algorithm is used for solution to obtain the optimal position of the UAV,so as to improve the capacity of the entire link.Performance analysis shows that compared with other similar models,the proposed UAV-LC model can improve the link capacity and enhance the resistance to dense-fog weather,and that even at a weather-affected attenuation factor of 80 dB/km,the UAV-LC model's link capacity can reach 4.8 Gb/s.关键词
