高空平台旋转对HAPS通信无线链路性能影响及抑制方法
Influence suppression of HAP's rotation on performance of wireless link for HAPS communication
摘要
Abstract
Recently,high altitude platform stations(HAPS)communication system has been identified as a promising and cost-effective service in the field of telecommunication.In a HAP system which formed by high altitude platforms combines the advantages of both terrestrial and satellite communication systems,also the HAPS communication system avoids the disadvantages of both terrestrial and satellite communication systems effectively. Obviously the high altitude platform(HAP)doesn't keep stationary all long.The state of instability of the HAP will impact the wireless link performance of HAPS communication seriously.All the research work considers that the high altitude platform moves vertically or horizontally or the high altitude platform keeps stationary.Traditional method can not eliminate influence on the wireless link performance of HAPS communication caused by the rotation of high altitude platform.Therefore,parameter characteristic system of high altitude platform's rotation states is constructed.Wireless link models will be constructed by adopting the combination of array antenna design, beamforming technology,cell coverage and cell allocation and high altitude platform's states.Influence suppression of high altitude platform's rotation state on performance of wireless link of HAPS communication is realized by these wireless link models.Bit error and signal interruption in signal covering blind areas during the signal transmission will be resolved.The performance of wireless link is guaranteed and signals will be transmitted reliably.关键词
