论文摘要
这项工作调查了新型卫星 - 事务（Satter）网络的安全性和可靠性分析。具体而言，卫星试图通过在存在窃听信息的窃听器的情况下通过多个继电器节点的支持将机密信息传输给地面用户（GU）。部署了友好的干扰器，以改善卫星和继电器之间的安全传输。此外，还部署了卫星到RICIAN通用的RICIAN褪色通道和不完美的通道状态信息（CSI）来检查一般系统模型。在这种情况下，出现停电概率（OP）和截距概率（IP）的闭合形式表达式是对应于基于放大的（AF）基于（AF）的继电器方案的，这是具有挑战性的，以前尚未研究过。最后，通过蒙特卡洛模拟验证了数学分析的精确性。此外，还检查了各种关键参数（例如，通道估计误差，卫星发射功率，继电器的发射功率，继电器数量和褪色严重性参数）的影响。
This work investigates the security and reliability analysis for a novel satellite-terrestrial (SatTer) network. Specifically, a satellite attempts to transmit confidential information to a ground user (GU) via the support of multiple relay nodes in the presence of an eavesdropper that tries to overhear the information. A friendly jammer is deployed to improve the secure transmission between the satellite and the relays. Furthermore, satellite-to-relay generalized Rician fading channels and imperfect channel state information (CSI) are deployed to examine a general system model. In this context, the closed-formed expressions for the outage probability (OP) and intercept probability (IP) are derived corresponding to an amplify-and-forward (AF)-based relaying scheme, which is challenging and has not been studied before. Finally, the exactness of the mathematical analyses is validated through Monte Carlo simulations. Furthermore, the effects of various key parameters (e.g., channel estimation errors, satellite's transmit power, relay's transmit power, number of relays, and fading severity parameter) are examined.
