Encoded Jamming Secure Communication for RIS-Assisted Systems
Hao Yang, Hao Xu, Kai Wan +2
This paper investigates a cooperative jamming (CJ)-aided secure wireless communication system. Conventional CJ schemes transmit Gaussian noise (GN) to improve security, which inher…
Sensing-Aided Secure Multicast in Two-Level Rotatable Antenna-Enabled ISAC Systems: Modeling and Optimization
Zequan Wang, Liang Yin, Hao Xu +3
In physical layer security, the channel state information (CSI) of passive eavesdroppers is usually difficult to obtain, which has motivated sensing-aided secure communication (SAS…
Rotatable and Movable Antenna-Enabled Near-Field Integrated Sensing and Communication
Yunan Sun, Hao Xu, Chongjun Ouyang +1
The aim of this article is to investigate the performance of near-field integrated sensing and communication (ISAC) systems using rotatable movable antennas (RMAs). In the proposed…
Spectral Efficiency Maximization for DMA-enabled Multiuser MISO with Statistical CSI
Hao Xu, Boyu Ning, Chongjun Ouyang +1
Dynamic metasurface antennas (DMAs) offer the potential to achieve large-scale antenna arrays with low power consumption and reduced hardware costs, making them a promising technol…
Uplink Sum Rate Maximization for Pinching Antenna-Assisted Multiuser MISO
Jiarui Zhang, Hao Xu, Chongjun Ouyang +2
This article investigates the application of pinching-antenna systems (PASS) in multiuser multiple-input single-output (MISO) communications. Two sum-rate maximization problems are…
