摘要/Abstract

摘要： 近年来，由高空平台构成的信息系统在通信领域的应用得到了广泛认同。高空平台站(HAPS, High Altitude Platform Stations)通信系统兼具卫星和陆地通信系统的优势，同时又有效避免了两者的缺点。高空平台不可能静止驻留在空中，平台的运动状态就会对HAPS通信无线链路性能产生关键影响。目前的研究都集中考虑平台简单运动（水平或垂直移动）或假设平台稳定，这些研究存在很大的局限性。因此，本文通过建立平台旋转状态特征参数体系，采取阵列天线设计、波束形成技术、小区覆盖与划分技术与平台状态相结合的方法，构建适合平台旋转状态下的无线链路模型，抑制平台旋转给HAPS通信链路性能带来的影响，解决高空平台旋转情况下HAPS通信无线链路存在误码、信号中断或传输信号盲区的问题，以保证无线链路性能，实现信号的可靠传输。

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.
