Covert Communications over Enormous Fluid Antenna Systems (E-FAS): Impact of Channel Hardening on Detection

Farshad Rostami Ghadi, Damoon Shahbaztabar, Kai-Kit Wong +1

Enormous fluid antenna systems (E-FAS) enable guided surface wave (SW) propagation and induce an end-to-end channel that is conditionally complex Gaussian with a random covariance…
