Joint Transmit and Pinching Beamforming for Pinching Antenna Systems (PASS): Optimization-Based or Learning-Based?
Xiaoxia Xu, Xidong Mu, Yuanwei Liu +1
A novel pinching antenna system (PASS)-enabled downlink multi-user multiple-input single-output (MISO) framework is proposed. PASS consists of multiple waveguides spanning over tho…
Multi-Mode Pinching Antenna Systems Enabled Multi-User Communications
Xiaoxia Xu, Xidong Mu, Yuanwei Liu +1
This paper proposes a novel multi-mode pinching-antenna systems (PASS) framework. Multiple data streams can be transmitted within a single waveguide through multiple guided modes,…
A Survey of Pinching-Antenna Systems (PASS)
Yuanwei Liu, Hao Jiang, Xu Gan +10
