Model and Evaluation for Performance Effects by Instability of HAP for HAPS Communication

Obviously the HAP doesn't keep stationary all long and the HAP state of rotation and swing will impact the performance of HAPS communication seriously.By far,all the research work assumed that the high altitude platform is stationary and offset caused by movement of the high altitude platform is compensated.Therefore traditional method can not resolve the problems caused by the instability of high altitude platform and effects on the performance of HAPS communication by instability of high altitude platform are researched profoundly.A wireless link model which reflects the states of HAP is proposed and the problems caused by the instability of high altitude platform are resolved.Lastly the validity of the model proposed uhis paper is proved by numerical analysis and simulation.
