A Deep Learning-based Low-Complexity SVD Approximation for Large-Scale MIMO Systems

The cubic complexity of singular value decomposition (SVD) has become a major bottleneck for real-time processing in large-scale multiple-input multiple-output (MIMO) systems. To address this issue, in this paper, we propose a deep learning-based low-complexity SVD approximation method tailored for such systems. The pr...

Artificial Noise Assisted Secure ISAC Beamforming Countering Covert Multiantenna Eavesdropper: A Symbol-Level Precoding Scheme

The current security designs in integrated sensing and communication (ISAC) systems frequently rely on prior information about the eavesdropper, such as location and channel state information (CSI). However, for the covert eavesdropper, the absence of prior information significantly degrades security performance. To ad...
