摘要 本文提出一种基于距离判决的高空平台站(HAPS)通信的动态信道分配(DCA)算法,通过对无线链路功率到收发链路距离的转化,实时监测HAPS通信的收发链路距离来进行无线信道分配,解决HAPS通信中由于负载不均等造成的无线资源无法满足用户需求的问题.通过与随机信道分配算法及最差可接受信道分配算法的性能进行比较,本文提出的基于距离判决的算法能够在阻塞概率稍微增加的情况下解决系统连接中断问题,有效地提高了系统的整体性能. To resolve the lack of wireless channel resource causing by load unbalance,a novel dynamic channel allocation algorithm in HAPS communication based on distance verdict is proposed through real-time monitor of distance which corresponded the transmit-receive power of wireless link.By comparison to two wireless channel allocation algorithms in literature,the call drop ratio is decreased greatly with slight blockage ratio increasing and the system performance is improved availably.
