Robust Beamforming and Power Allocation for Coherent Cell-Free Massive MIMO with Residual Calibration Errors
Mingjun Sun, Xidong Mu, Shaochuan Wu +2
This paper investigates robust downlink transmission to tolerate calibration aging in time-division duplex cell-free massive multiple-input multiple-output (CF-mMIMO) systems with…
B2X Networks: Joint Design of Communication and Control for Embodied Intelligence
Yuanwei Liu, Xu Gan, Zhaolin Wang +5
This article proposes the concept of \emph{brain-body-to-everything (B2X)} networks to facilitate the integration of wireless networks and embodied intelligence. In this framework,…
Pinching Antennas-Assisted Sensing: A Ziv-Zakai Bound (ZZB) Perspective
Hao Jiang, Chongjun Ouyang, Yuanwei Liu +2
The sensing capability of the pinching-antenna system (PASS) is analyzed from a Ziv-Zakai bound (ZZB) perspective, motivated by the sensing ambiguity arising from the multimodal ob…
Access Protocols for Segmented Waveguide-Enabled Pinching-Antenna Systems (SWANs)
Shan Shan, Chongjun Ouyang, Petar Popovski +1
This paper proposes an access protocol framework for segmented waveguide-enabled pinching-antenna systems (SWANs), which exploits SWAN-induced reconfigurable channel diversity as a…
Joint Segment Activation and Antenna Placement for Uplink SWAN Systems
Songnan Gu, Zhenqiao Cheng, Hao Jiang +3
This article analyzes the achievable sum-rate of multiuser uplink segmented waveguide-enabled pinching-antenna systems (SWANs). To unveil system-design insights, an upper bound on…
Electromagnetic Signal and Information Theory: A Continuous-Aperture Array Perspective
Zhaolin Wang, Chongjun Ouyang, Kuranage Roche Rayan Ranasinghe +4
Emerging wireless systems are evolving toward larger, denser, higher-frequency, and more reconfigurable apertures, which motivates the study of continuous-aperture arrays (CAPAs).…
