摘要

本文提出了一种新的两阶段方法，专门用于在存在非合作干扰节点（INs）的A2G（空对地）信道中构建信道知识图（ckm）。我们首先基于总接收信号强度测量和环境拓扑构建的期望通信信号强度图估计采样位置的干扰信号强度（ISS）。其次，提出了一个国际空间站地图构建网络（IMNet），其中包括负值校正模块，以实现精确重建。随后，我们进一步执行信噪比图构建和IN定位。仿真结果表明，在存在干扰的情况下，与基线相比，所提出的IMNet的构造误差较小。

IMNet: Interference-Aware Channel Knowledge Map Construction and Localization

This letter presents a novel two-stage method for constructing channel knowledge maps (CKMs) specifically for A2G (Aerial-to-Ground) channels in the presence of non-cooperative interfering nodes (INs). We first estimate the interfering signal strength (ISS) at sampling locations based on total received signal strength measurements and the desired communication signal strength (DSS) map constructed with environmental topology. Next, an ISS map construction network (IMNet) is proposed, where a negative value correction module is included to enable precise reconstruction. Subsequently, we further execute signal-to-interference-plus-noise ratio map construction and IN localization. Simulation results demonstrate lower construction error of the proposed IMNet compared to baselines in the presence of interference.
