Practical Wi-Fi-based Motion Recognition Under Variable Traffic Patterns
Guolin Yin, Junqing Zhang, Guanxiong Shen +1
Wi-Fi sensing detects human motions and activities by analysing the channel state information (CSI) derived from Wi-Fi transmissions. However, the impact of variable transmission t…
Hiding Secrets in the CSI Quotient: A Robust Wi-Fi CSI Steganography System
Jiamu Guo, Hailang Jia, Guanxiong Shen +3
Physical layer (PHY) steganography conceals secrets by making subtle modifications to transmitted radio waveforms, which can be applied to establish covert communication systems. G…
Secure Communication in MIMOME Movable-Antenna Systems with Statistical Eavesdropper CSI
Lei Xie, Peilan Wang, Guanxiong Shen +3
This paper investigates the potential of movable antennas (MAs) to enhance physical layer security within a multiple-input multiple-output multiple-antenna eavesdropper (MIMOME) sy…
