Through-Wall Imaging based on WiFi Channel State Information
This work presents a seminal approach for synthesizing images from WiFi Channel State Information (CSI) in through-wall scenarios.
Directional Antenna Systems for Long-Range Through-Wall Human Activity Recognition
For the core NLOS activity recognition problem, the biquad antenna and PIFA-based systems achieve accuracies of 92. 0$\pm$3. 5 and 86. 8$\pm$4. 7, respectively, demonstrating the feasibility of long-range through-wall HAR with the proposed systems.
Data Augmentation Techniques for Cross-Domain WiFi CSI-based Human Activity Recognition
To address this issue, in this work, data augmentation techniques commonly used in image-based learning are applied to WiFi CSI to investigate their effects on model generalization performance in cross-scenario and cross-system settings.
