Air-to-Ground Cooperative OAM Communications
Ruirui Chen, Yu Ding, Beibei Zhang +2
For users in hotspot region, orbital angular momentum (OAM) can realize multifold increase of spectrum efficiency (SE), and the flying base station (FBS) can rapidly support the re…
Precoding Based Downlink OAM-MIMO Communications with Rate Splitting
Ruirui Chen, Jinyang Lin, Beibei Zhang +2
Orbital angular momentum (OAM) and rate splitting (RS) are the potential key techniques for the future wireless communications. As a new orthogonal resource, OAM can achieve the mu…
Joint Power Allocation and Placement Scheme for UAV-assisted IoT with QoS Guarantee
Ruirui Chen, Yanjing Sun, Liping Liang +1
In the disaster and remote regions, unmanned aerial vehicles (UAVs) can assist the data acquisition for Internet of Things (IoT). How to cover massive IoT devices (IDs), which requ…
Cooperative Orbital Angular Momentum Wireless Communications
Ruirui Chen, Wenchi Cheng, Jinyang Lin +1
Orbital angular momentum (OAM) mode multiplexing has the potential to achieve high spectrum-efficiency communications at the same time and frequency by using orthogonal mode resour…
Reconfigurable-Intelligent-Surface Assisted Orbital-Angular-Momentum Secure Communications
Minmin Wang, Liping Liang, Wenchi Cheng +3
As a kind of wavefront with helical phase, orbital angular momentum (OAM) shows the great potential to enhance the security results of wireless communications due to its unique ort…
Lifelong Event Detection with Embedding Space Separation and Compaction
Chengwei Qin, Ruirui Chen, Ruochen Zhao +2
To mitigate forgetting, existing lifelong event detection methods typically maintain a memory module and replay the stored memory data during the learning of a new task. However, t…
