On Covert Communication With Noise Uncertainty

He, Biao; Yan, Shihao; Lau, Vincent K. N.; Zhou, Xiangyun


Prior studies on covert communication with noise uncertainty adopted a worst-case approach from the warden’s perspective. That is, the worst-case detection performance of the warden is used to assess covertness, which is overly optimistic. Instead of simply considering the worst limit, in this work, we take the distribution of noise uncertainty into account to evaluate the overall covertness in a statistical sense. Specifically, we define new metrics for measuring the covertness, which...[Show more]
