Abstract
高空平台(high altitude platform,HAP)通信以其低成本和广覆盖的优点受到较高的关注,其部署特征有利于多媒体广播的应用.引入多HAP广播与单播的功率域非正交复用(power domain non-orthogonal multiplexing,PD-NOM)方案,将广播信号与单播信号在功率域叠加后实现同时同频传输,能有效克服现有正交时分复用(orthogonal time-division multiplexing,OTDM)方案中广播与单播抢占系统资源的问题.通过PD-NOM方案与OTDM方案的用户单播容量和广播容量的仿真和分析,结果表明,在单播容量一致的情况下,采用PD-NOM方案的小区广播平均容量相对OTDM方案有显著提升,在典型的3个HAP覆盖场景下,PD-NOM相对OTDM的广播容量增益可高达150%.
