Uncertainty-Weighted Multi-Task CNN for Joint DoA and Rain-Rate Estimation Under Rain-Induced Array Distortions
Chenyang Yan, Ruonan Yang, Shunqiao Sun +1
We investigate joint direction-of-arrival (DoA) and rain-rate estimation for a uniform linear array operating under rain-induced multiplicative distortions. Building on a wavefront…
Measurements and Modeling of Air-Ground Integrated Channel in Forest Environment Based on OFDM Signals
Zhe Xiao, Shu Sun, Na Liu +2
Forests are frequently impacted by climate conditions, vegetation density, and intricate terrain and geology, which contribute to natural disasters. Personnel engaged in or support…
Low-Latency Terrestrial Interference Detection for Satellite-to-Device Communications
Runnan Liu, Weifeng Zhu, Shu Sun +1
Direct satellite-to-device communication is a promising future direction due to its lower latency and enhanced efficiency. However, intermittent and unpredictable terrestrial inter…
Channel Gain Map Construction based on Subregional Learning and Prediction
Jiayi Chen, Ruifeng Gao, Jue Wang +2
The construction of channel gain map (CGM) is essential for realizing environment-aware wireless communications expected in 6G, for which a fundamental problem is how to predict th…
Integrated Sensing and Communications for Low-Altitude Economy: A Deep Reinforcement Learning Approach
Xiaowen Ye, Yuyi Mao, Xianghao Yu +3
This paper studies an integrated sensing and communications (ISAC) system for low-altitude economy (LAE), where a ground base station (GBS) provides communication and navigation se…
Two-Stage Radio Map Construction with Real Environments and Sparse Measurements
Yifan Wang, Shu Sun, Na Liu +2
Radio map construction based on extensive measurements is accurate but expensive and time-consuming, while environment-aware radio map estimation reduces the costs at the expense o…
