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），其中机会主义的地面陆网互联网（IoT）网络有助于主要卫星通信，并访问从从层次上获得的混合干扰下的频谱，以从外星外部来源（ETSS）和Terrestrestrial Sources（TSS）（tssssssssss）获得频谱。本文中，物联网网络采用电源域多路复用，以放大超级卫星和物联网信号。 Considering a unified analytical framework for shadowed-Rician fading with integer/non-integer Nakagami-\emph{m} parameter for satellite and interfering ETSs links along with the integer/non-integer Nakagami-\emph{m} fading for terrestrial IoT and interfering TSs links, we derive the outage probability (OP) of both satellite和物联网网络。此外，我们得出了各自的渐近OP表达式，以在这两个条件下揭示卫星和物联网网络的多样性顺序，即当干扰物的传输能力时：$（a）$保持固定； $（b）$与主要卫星和物联网用户的传输功率成正比。我们表明，具有自适应功率分解因子的拟议的OSTN受益于物联网网络，同时保证了卫星网络的某些服务质量（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 internet-of-things (IoT) network assists the primary satellite communications as well as accesses the spectrum for its own communications under hybrid interference received from extra-terrestrial sources (ETSs) and terrestrial sources (TSs). Herein, the IoT network adopts power-domain multiplexing to amplify-and-forward the superposed satellite and IoT signals. Considering a unified analytical framework for shadowed-Rician fading with integer/non-integer Nakagami-\emph{m} parameter for satellite and interfering ETSs links along with the integer/non-integer Nakagami-\emph{m} fading for terrestrial IoT and interfering TSs links, we derive the outage probability (OP) of both satellite and IoT networks. Further, we derive the respective asymptotic OP expressions to reveal the diversity order of both satellite and IoT networks under the two conditions, namely when the transmit power of interferers: $(a)$ remains fixed; and $(b)$ varies proportional to the transmit powers of main satellite and IoT users. We show that the proposed OSTN with adaptive power-splitting factor benefits the IoT network while guaranteeing certain quality-of-service (QoS) of satellite network. We verify the numerical results by simulations.
