提出了基于全频率复用的异构卫星网络，其中卫星和地面网络在同一子信道上传输。点间波束干扰和系统间干扰（来自地面基站的干扰）是限制卫星用户性能的主要因素。在这项工作中，提出了一种新的方法，其中只有占主导地位的干扰信号被缓解，而忽略了其他干扰信号。为了抑制显性干扰信号，提出了干扰感知检测器。重点研究了基于连续干扰消除器和联合解码器的干扰抑制策略。通过蒙特卡罗仿真，证明了联合解码器与无干扰检测器和逐次干扰消除器相比的鲁棒性。
Full frequency reuse based heterogeneous satellite networks, where the satellite and terrestrial networks transmit on the same sub channel, is proposed. The inter spot beam interference and inter system interference (interference from the terrestrial base station) are the major performance-limiting factors at the satellite user. In this work, a novel approach, where only the dominant interfering signal is mitigated while ignoring the other interfering signals, is proposed. Interference-aware detector is proposed to mitigate the dominant interfering signal. In particular, successive interference canceler and joint decoder based interference mitigation strategies are investigated. The robustness of the joint decoder compared to that of the interference ignorant detector and successive interference canceler is proved through Monte-Carlo simulations.
