Abstract: In covert communications, the position of the warden has a variety of situations, which leads to different scenes that require different covert communication schemes to ensure the security.
Abstract: In this letter, we investigate the joint optimization of transmit power allocation and receive/passive beamforming in a reconfigurable intelligent surface (RIS)-assisted uplink two-user rate ...
Abstract: Stacked intelligent metasurfaces (SIMs), which integrate multiple programmable metasurface layers, have recently emerged as a promising technology for advanced wave-domain signal processing.
Abstract: In this paper, we investigate an integrated sensing and communication (ISAC) system assisted by a dynamic metasurface antenna (DMA), where the base station (BS) simultaneously communicates ...
Abstract: This work investigates secure transmission in non-orthogonal multiple access (NOMA)-integrated sensing and communication (ISAC) systems, where legitimate users may act as internal ...
Abstract: In this paper, we investigate the secure transmission design for simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS)-assisted multiple-input ...
Abstract: To enhance the massive connectivity and spectral efficiency of Internet-of-Things applications supporting batteryless devices, we integrate active intelligent reflecting surface (IRS) into ...
Abstract: The pinching-antenna system (PASS) reconfigures wireless links through pinching beamforming, in which the activated locations of pinching antennas (PAs) along dielectric waveguides are ...
