论文摘要
在本文中，我们考虑了一个覆盖的卫星 - 事物网络（OSTN），其中一个机会主义选择的陆地物联网网络有助于初级卫星通信，并在存在外事物外和地面源的联合干扰的情况下访问其自身通信的频谱。在此，通过将其适当的卫星和物联网信号中的电源分开，可以通过IoT网络采用电源域多路复用。依靠放大和前向（AF）的机会性IoT网络选择策略，从而最大程度地减少了卫星网络的中断概率（OP），我们得出了卫星和IoT网络的封闭形式的下限OP表达式。我们进一步得出相应的渐近op表达式，以检查两个网络的可实现多样性顺序。我们表明，具有自适应功率分配因子的拟议OSTN受益于物联网网络，同时保证卫星网络的服务质量（QoS）。我们通过模拟验证数值结果。
In this paper, we consider an overlay satellite-terrestrial network (OSTN) where an opportunistically selected terrestrial IoT network assist primary satellite communications as well as access the spectrum for its own communications in the presence of combined interference from extra-terrestrial and terrestrial sources. Hereby, a power domain multiplexing is adopted by the IoT network by splitting its power appropriately among the satellite and IoT signals. Relying upon an amplify-and-forward (AF)-based opportunistic IoT network selection strategy that minimizes the outage probability (OP) of satellite network, we derive the closed-form lower bound OP expressions for both the satellite and IoT networks. We further derive the corresponding asymptotic OP expressions to examine the achievable diversity order of two networks. We show that the proposed OSTN with adaptive power splitting factor benefits IoT network while guaranteeing the quality of service (QoS) of satellite network. We verify the numerical results by simulations.
