Abstract: This paper focuses on maximizing the sum secrecy rate in secure multi-user MISO communication systems that use stacked intelligent metasurfaces (SIM). SIM technology manipulates ...
Abstract: This letter introduces pilot-based codebook artificial noise (PCAN) into movable antenna (MA)-enabled MIMO communication systems. It investigates the problem of optimizing secrecy capacity ...
Abstract: Simultaneous wireless information and power transfer (SWIPT) and non-orthogonal multiple access (NOMA) enable efficient data-power transfer and massive connectivity but suffer from channel ...
Abstract: Wireless communications involving unmanned aerial vehicles (UAVs) are more vulnerable to the malicious jamming. As a promising solution, intelligent reflecting surface (IRS) can be equipped ...
Abstract: This paper investigates an innovative movable antenna (MA)-enhanced multiple-input multiple-output (MIMO) system designed to enhance communication performance. We aim to maximize the energy ...
Abstract: In this paper, a reconfigurable intelligent surface(RIS)-assisted millimeter-wave (mmWave) non-orthogonal multiple access (NOMA) communication system is considered, where the RIS is ...
