A Survey of Intelligent Methods Under Inadequate Pilots in 5G/6G MIMO Systems: Pilot-Domain Mitigation, Channel Estimation, and Receiver Processing

In large-scale multiple-input multiple-output (MIMO) systems, inadequate pilots can necessitate pilot reuse, reducing channel-estimation accuracy, while too few received pilot observations can also lead to inaccurate interference-plus-noise covariance estimates. These estimation errors can further degrade the performan...

Ada-MGNS: Enhancing Black-Box Transfer Attacks on Vision Transformers via Adaptive Momentum and Deep Attention Guidance

Transfer-based black-box attacks are an important tool for evaluating deployed vision models, yet adversarial examples generated from Vision Transformer (ViT) surrogates often exhibit limited cross-architecture transferability. Existing momentum-based attacks are effective for convolutional neural network (CNN) surroga...
