Robust Beamforming for Pinching-Antenna Systems
Mingjun Sun, Chongjun Ouyang, Shaochuan Wu +1
Pinching-antenna system (PASS) mitigates large-scale path loss by enabling flexible placement of pinching antennas (PAs) along the dielectric waveguide. However, most existing stud…
Multiuser Beamforming for Pinching-Antenna Systems: An Element-wise Optimization Framework
Mingjun Sun, Chongjun Ouyang, Shaochuan Wu +1
The pinching-antenna system (PASS) reconstructs wireless channels through pinching beamforming, i.e., optimizing the activated locations of pinching antennas (PAs) along the wavegu…
Physical Layer Security for Pinching-Antenna Systems (PASS)
Mingjun Sun, Chongjun Ouyang, Shaochuan Wu +1
The pinching-antenna system (PASS) introduces new degrees of freedom (DoFs) for physical layer security (PLS) through pinching beamforming. In this paper, a couple of scenarios for…
Secure Beamforming for Continuous Aperture Array (CAPA) Systems
Mingjun Sun, Chongjun Ouyang, Zhaolin Wang +2
Continuous aperture array (CAPA) is considered a promising technology for 6G networks, offering the potential to fully exploit spatial DoFs and achieve the theoretical limits of ch…
