Oto-Meal: Earable Sensing with PPG and IMU for Personalized Meal Awareness
Yuxuan Hou, Jiao Li, Linshan Jiang +1
Meal awareness can help people reflect on hydration, chewing rhythm, and conversation-heavy meals, but many eating-sensing approaches rely on cameras, microphones, food photographs…
Heuristic Solution to Joint Deployment and Beamforming Design for STAR-RIS Aided Networks
Bai Yan, Qi Zhao, Jin Zhang +1
This paper tackles the deployment challenges of Simultaneous Transmitting and Reflecting Reconfigurable Intelligent Surface (STAR-RIS) in communication systems. Unlike existing wor…
Joint Deployment and Beamforming Design of Aerial STAR-RIS Aided Networks with Reinforcement Learning
Zhuoyuan Ma, Qi Zhao, Jin Zhang +1
Aerial simultaneous transmitting and reflecting reconfigurable intelligent surfaces (STAR-RIS) enables full-space coverage in dynamic wireless networks. However, most existing work…
Multiobjective Bilevel Evolutionary Approach for Off-Grid Direction-of-Arrival Estimation
Bai Yan, Qi Zhao, Jin Zhang +2
The source number identification is an essential step in direction-of-arrival (DOA) estimation. Existing methods may provide a wrong source number due to inferior statistical prope…
