Treating Interference as Noise is Optimal for Covert Communication over Interference Channels

Kang-Hee Cho, Si-Hyeon Lee

We study the covert communication over K-user discrete memoryless interference channels (DM-ICs) with a warden. It is assumed that the warden's channel output distribution induced…

Throughput Scaling of Covert Communication over Wireless Adhoc Networks

Kang-Hee Cho, Si-Hyeon Lee, Vincent Y. F. Tan

We consider the problem of covert communication over wireless adhoc networks in which (roughly) $n$ legitimate nodes (LNs) and $n^{κ}$ for $0 < κ < 1$ non-communicating warden nodes (WNs…
