Radio Map Updating from Streaming Spectrum Measurements via Memory-Based Online Gaussian Processes
Yuanyuan Deng, Bo Zhou, Tian Chen +5
Radio maps, which estimate spatial radio-frequency characteristics from spectrum measurements, are essential for applications such as spectrum management and network planning. With…
Sensing-Aided Channel Estimation for Near-Field MIMO ISAC Systems via Cross-Attention Transformer
Peihao Dong, Renbin Li, Shen Gao +4
Near-field integrated sensing and communication (ISAC) can deliver the high spatial resolution and transmission capability with the shared spectrum and hardware. Due to the partial…
UAV-Aided Progressive Interference Source Localization Based on Improved Trust Region Optimization
Guochen Gu, Zhipeng Lin, Qiuming Zhu +5
Trust region optimization-based received signal strength indicator (RSSI) interference source localization methods have been widely used in low-altitude research. However, these me…
3D Spectrum Mapping and Reconstruction under Multi-Radiation Source Scenarios
Wang Jie, Lin Zhipeng, Zhu Qiuming +5
Spectrum map construction, which is crucial in cognitive radio (CR) system, visualizes the invisible space of the electromagnetic spectrum for spectrum-resource management and allo…
