Abstract
We disclose a novel methodology for wireless networks that optimizes the transmission probability, transmit power at an agent, and the reflection matrix of an IRS for covert RF communications. Key features include: (1) An exact closed-form expression for the expected detection error probability (DEP) at an adversary is provided considering the transmission probability at the agent; and (2) a novel method to optimize the transmission probability, transmit power at the agent and the reflection matrix of the IRS with the goal of maximizing the achievable rate at a client while ensuring a covertness constraint is developed. More specifically, the method may require only one-dimensional line search schemes, achieves near-optimal performance, and exhibits enhanced achievable data rate when compared to the conventional technique without the transmission probability optimization.
