Secure Multicast Communications with Pinching-Antenna Systems (PASS)
Shan Shan, Chongjun Ouyang, Yong Li +1
This article investigates secure multicast communications in pinching-antenna systems (PASS), where pinching beamforming is enabled by adaptively adjusting pinching antenna (PAs) p…
Multigroup Multicast Design for Pinching-Antenna Systems: Waveguide-Division or Waveguide-Multiplexing?
Shan Shan, Chongjun Ouyang, Yong Li +1
This article addresses the design of multigroup multicast communications in the pinching-antenna system (PASS). A PASS-enabled multigroup transmission framework is proposed to maxi…
Exploiting Pinching-Antenna Systems in Multicast Communications
Shan Shan, Chongjun Ouyang, Yong Li +1
The pinching-antenna system (PASS) reconfigures wireless links through pinching beamforming, in which the activated locations of pinching antennas (PAs) along dielectric waveguides…
Flexible WMMSE Beamforming for MU-MIMO Movable Antenna Communications
Songjie Yang, Zihang Wan, Yue Xiu +4
Movable antennas offer new potential for wireless communication by introducing degrees of freedom in antenna positioning, which has recently been explored for improving sum rates.…
