Radio Map-Enabled 3D Trajectory and Communication Optimization for Low-Altitude Air-Ground Cooperation
Menghao Hu, Tong Zhang, Shuai Wang +4
Low-altitude economy includes the application of unmanned aerial vehicles (UAVs) serving ground robots. This paper investigates the 3-dimensional (3D) trajectory and communication…
An Efficient Sum-Rate Maximization Algorithm for Fluid Antenna-Assisted ISAC System
Qian Zhang, Mingjie Shao, Tong Zhang +3
This letter investigates a fluid antenna (FA)-assisted integrated sensing and communication (ISAC) system, with joint antenna position optimization and waveform design. We consider…
Rate-Splitting and Sum-DoF for the K-User MISO Broadcast Channel with Mixed CSIT and Order-(K-1) Messages
Shuo Zheng, Tong Zhang, Jingfu Li +4
In this paper, we propose a rate-splitting design and characterize the sum-degrees-of-freedom (DoF) for the K-user multiple-input-single-output (MISO) broadcast channel with mixed…
Integrated Robotics Networks with Co-optimization of Drone Placement and Air-Ground Communications
Menghao Hu, Tong Zhang, Shuai Wang +4
Terrestrial robots, i.e., unmanned ground vehicles (UGVs), and aerial robots, i.e., unmanned aerial vehicles (UAVs), operate in separate spaces. To exploit their complementary feat…
